A. 6.38 METERS
B. 3.69 METERS
(a) To compute fg=(5,0.2,9.8), plug the values into the formula: d = v^2 / 2µg.
d = (5^2) / (2 * 0.2 * 9.8) = 25 / 3.92 ≈ 6.38 meters
This means that if a car is driving at 5 m/s with a friction coefficient of 0.2 and gravity of 9.8 m/s^2, it will leave a skid mark of approximately 6.38 meters when it brakes suddenly.
(b) Now, let's compute the length of the skid mark for the given values and then use differentials to approximate the change in skid length:
Given: v = 5 m/s, µ = 0.2, g = 9.8 m/s^2
Initial skid length, d = v^2 / 2µg = (5^2) / (2 * 0.2 * 9.8) ≈ 6.38 meters
Now, let's find the change in skid length when v increases to 5.2 m/s and µ decreases to 0.1.
Change in velocity, dv = 5.2 - 5 = 0.2 m/s
Change in friction coefficient, dµ = 0.1 - 0.2 = -0.1
We can approximate the change in skid length using differentials:
dd ≈ (dv * ∂d/∂v) + (dµ * ∂d/∂µ)
Here, ∂d/∂v = v / µg and ∂d/∂µ = -v^2 / (2µ^2g)
So, dd ≈ (0.2 * (5 / (0.2 * 9.8))) + (-0.1 * (-25 / (2 * 0.2^2 * 9.8))) ≈ 0.51 + 3.18 ≈ 3.69 meters
Thus, the change in skid length is approximately 3.69 meters when the velocity increases to 5.2 m/s and the friction coefficient decreases to 0.1.

following forces has caused her to slow down?
A. Gravity
B. Ground reaction force
C. Muscle force
D. Friction
When Lana is gliding across the pond on ice skates. By the time she makes it to the other side of the pond, she has nearly come to a complete stop. Friction forces has caused her to slow down. Hence option D is correct.
When two surfaces move relative to each other, the friction between them turns kinetic energy into thermal energy (that is, work to heat). As demonstrated by the utilisation of friction caused by rubbing pieces of wood together to ignite a fire, this feature may have severe repercussions. When motion with friction occurs, such as when a viscous fluid is churned, kinetic energy is transformed to thermal energy. Another significant effect of many forms of friction is wear, which can lead to performance deterioration or component damage. The science of tribology includes friction. Ice skates are metal blades affixed to the bearer's feet that are used to drive the bearer across a sheet of ice when ice skating.
Hence option D is correct.

32g of water at 60°C is poured into 60g of cold water at 15°C, which is contained in a
calorimeter of mass 40g, and S.H.C of water is 0.1Jg'K'. Neglecting heat loss show that
the resulting temperature is 29°C.
Explanation:
Let thermal capacity of the vessel be C' J K-1
Heat energy given by hot water = 40 x 4.2 x (60 - 30) = 5040 J
Heat energy taken by cold water = 50 x 4.2 x (30 - 20) = 2100 J
Heat energy taken by vessel = C' x (30 - 20) = 10 C' J
If there is no loss of heat energy,
Heat energy given by hot water = Heat energy taken by cold water and vessel
or 5040 = 2100 + 10 C'
or 10 C' = 2940
or C'= 294 J K-1
Thus, thermal capacity of vessel = 294 J K-1.

An extension cord made of two wires of diameter 0.129 cm (no. 16 copper wire) and of length 2.4 m (8 ft) is connected to an electric heater which draws 13.5 A on a 120-V line. How much power is dissipated in the cord?
The power dissipated in the cord that is made up of two wires of diameter 0.129 cm (no. 16 copper wire) and length, 2.4 m (8 ft) that is connected to an electric heater which draws 13.5 A on a 120-V line is 191.40 W.
How to find the power dissipated in the cord?
The diameter of each wire = 0.129 cm length of the cord = 2.4 current through the wire = 13.5 A, Voltage across the wire = 120 V.
For no. 16 wire the resistance per unit length is 4.016 × 10-3 Ω/m. The resistance of each wire is R = ρl/A, where ρ = resistivity, l = length of the wire, A = area of the cross-section of the wire, and diameter of the wire = 0.129 cm. So, radius = d/2 = 0.0645 cm = 6.45 × 10-4 m
A = πr² = π(6.45 × 10-4 m)² = 3.289 × 10-7 m²
Area of a cross-section of each wire = 2 × 3.289 × 10-7 m² = 6.578 × 10-7 m²
The resistance per unit length of no. 16 wire is 4.016 × 10-3 Ω/m.
So, the resistance of each wire is R = (4.016 × 10-3 Ω/m) × (2.4 m) / (6.578 × 10-7 m²)= 1462.42 Ω
The total resistance of the wire is RT = 2R = 2 × 1462.42 Ω= 2924.84 Ω
Now, the power dissipated in the cord is P = I²R= (13.5 A)² × 2924.84 Ω= 191.40 W
Therefore, the power dissipated in the cord that is made up of two wires of diameter 0.129 cm (no. 16 copper wire) and length 2.4 m (8 ft) that is connected to an electric heater which draws 13.5 A on a 120-V line is 191.40 W.

Your 1000-m-long starship has warning lights at each end that, to you, flash simultaneously every minute. You are moving directly away from the planet Zerkon at 0.70c.
To a Zerkonian, do the lights flash simultaneously? If not, which flashes first-the light at the front of your ship or the trailing one?
Answer Choices:
A. The lights flash simultaneously.
B. The front light flashes first.
C. The trailing light flashes first.
D. Not enough information given to answer the question.
To a Zerkonian observer, the lights on your starship do not flash simultaneously. The trailing light flashes first.
This is due to the phenomenon of time dilation, predicted by Einstein's theory of relativity. As you, the observer on the starship, are moving away from the planet Zerkon at a high velocity of 0.70c (70% of the speed of light), time appears to be passing slower for you relative to the stationary frame of reference on Zerkon. As a result, the time interval between the flashes of the warning lights, which is one minute in your frame of reference, will be dilated or stretched from the perspective of the Zerkonian observer. The light at the front of your starship, which is moving away from Zerkon, takes longer to reach the observer compared to the light at the trailing end. Therefore, the trailing light will be observed to flash first by the Zerkonian observer. Hence, the correct answer is C. The trailing light flashes first.

Required:
a. Find the speed of the skydiver when the parachute opens.
b. Find the distance fallen before the parachute opens.
c. What is the limiting velocity v_L after the parachute opens?
A skydiver weighing 180 lb (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute after 10 s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.75|v| when the parachute is closed and is of magnitude 12|v| when the parachute is open, where the velocity v is measured in ft/s.
a. The speed of the skydiver when the parachute opens is 71.06 m/s.
b. The distance fallen before the parachute opens is 1,610 ft.
c. The limiting velocity \(v_L\) after the parachute opens is 66.71 m/s.
a. To find the speed of the skydiver when the parachute opens, we can use the concept of net force and Newton's second law of motion. The net force acting on the skydiver is given by:
\(F_n_e_t = m * a,\)
where \(F_n_e_t\) is the net force, m is the mass of the skydiver, and a is the acceleration.
Initially, during free fall, the net force is the difference between the weight of the skydiver and the force of air resistance:
\(F_n_e_t = m * g - F_a_i_r\)
where g is the acceleration due to gravity.
When the parachute opens, the force of air resistance changes to 12|v|, where v is the velocity of the skydiver.
For free fall:
\(m * g - F_a_i_r_c_l_o_s_e_d = m * a,\)
When the parachute opens:
\(m * g - F_a_i_r_o_p_e_n = m * a,\)
Since both equations are equal to m * a, we can set them equal to each other:
\(m * g - F_a_i_r_c_l_o_s_e_d = m * g - F_a_i_r_o_p_e_n\\F_a_i_r_o_p_e_n - F_a_i_r_c_l_o_s_e_d = m * g\).
Substituting the given values:
12|v| - 0.75|v| = 180 lb * g,
11.25|v| = 180 lb * g.
Converting the weight from lb to kg:
m = 180 lb * (1 kg / 2.205 lb) ≈ 81.63 kg.
Converting the acceleration due to gravity from ft/s² to m/s²:
g = 9.8 m/s².
11.25|v| = 81.63 kg * 9.8 m/s².
Solving for |v|:
|v| = (81.63 kg * 9.8 m/s²) / 11.25 ≈ 71.06 m/s.
Therefore, the speed of the skydiver when the parachute opens is approximately 71.06 m/s.
b. To find the distance fallen before the parachute opens, we can use the equation of motion:
\(d = v_0 * t + (1/2) * a * t^2\)
where d is the distance fallen, \(v_0\)is the initial velocity, t is the time, and a is the acceleration.
In this case, the skydiver falls for 10 s with an initial velocity of 0 ft/s and an acceleration of g. Substituting the values:
d = 0 ft/s * 10 s + (1/2) * (32.2 ft/s²) * (10 s)² ≈ 1,610 ft.
Therefore, the distance fallen before the parachute opens is approximately 1,610 ft.
c. The limiting velocity (\(v_L\)) is the maximum velocity the skydiver can reach after the parachute opens. It occurs when the force of air resistance is equal in magnitude to the weight of the skydiver.
\(m * g = F_a_i_r_o_p_e_n.\)
Substituting the given values:
180 lb * g = 12|\(v_L\)|.
Simplifying the equation:
|\(v_L\)| = (180 lb * g) / 12.
Converting the weight from lb to kg:
m = 180 lb * (1 kg / 2.205 lb) ≈ 81.63 kg.
Converting the acceleration due to gravity from ft/s² to m/s²:
g = 9.8 m/s².
|\(v_L\)| = (81.63 kg * 9.8 m/s²) / 12 ≈ 66.71 m/s.
Therefore, the limiting velocity (\(v_L\)) after the parachute opens is approximately 66.71 m/s.

How can you convince your friend that a beam of light from a laser pointer travels to a wall along a straight line? (a) Tell him that light rays travel in straight lines. (b) Sprinkle chalk dust along the laser beam. (c) Try to move along the laser beam blocking its light and note the light path. (d) Both b and c will work. (e) All answers (a)–(c) will work.
The correct answer is (e) All answers (a)-(c) will work.
(a) By explaining to your friend that light rays travel in straight lines, you can help them understand the concept. Light behaves as a form of electromagnetic radiation and typically travels in straight paths called rays. This property is known as rectilinear propagation.
(b) Sprinkling chalk dust along the laser beam can make the path of the light visible. When the light interacts with the chalk dust particles, it scatters in all directions, making the beam's trajectory clearly visible. This can help your friend see that the laser light is indeed traveling in a straight line.
(c) By attempting to move along the laser beam and blocking its light, you can demonstrate that the light path remains unaffected as you move. If the light were to curve or deviate from a straight line, you would notice a change in the light's direction as you block it. However, since the light continues to move in a straight line even when you obstruct it, it supports the notion that the laser beam travels along a straight path.
Using a combination of these approaches, you can provide convincing evidence to your friend that a beam of light from a laser pointer travels to a wall along a straight line.
