Sam travels 910.6 meters before he finally coasts to a stop.

To solve this problem, we need to find the distance traveled by Sam during the 9.0 s when the skis were powered and then add the distance traveled during the coasting phase until he stops.

First, let's find the acceleration of Sam during the powered phase:

The net force on Sam is the force of thrust minus the force of friction:

net force = thrust - friction

net force = \(190 N - (0.1)(79 kg)(9.81 m/s^2) = 111.23 N\)

Using Newton's second law, we can find the acceleration of Sam:

net force = mass x acceleration

111.23 N = 79 kg x acceleration

acceleration = 1.41 m/s^2

The distance traveled during the powered phase is given by:

distance powered = initial velocity x time + 0.5 x acceleration x time^2

The initial velocity is zero, so the distance traveled during the powered phase is:

distance powered = 0.5 x acceleration x time^2

distance powered = 0.5 x 1.41 m/s^2 x (9.0 s)^2

distance powered = 56.9 m

Now Sam coasts until he stops. During this phase, the only force acting on him is friction, so we can use the following equation to find the distance traveled:

distance coasting = initial velocity x time + 0.5 x friction x time^2

The initial velocity is the velocity Sam had at the end of the powered phase. To find this, we use the equation:

velocity = acceleration x time

velocity = 1.41 m/s^2 x 9.0 s

velocity = 12.7 m/s

So the distance traveled during the coasting phase is:

distance coasting =\(12.7 m/s x t + 0.5 x (0.1)(79 kg)(9.81 m/s^2) x t^2\)

We want to find the total distance traveled, so we need to add the distance traveled during the powered phase to the distance traveled during the coasting phase:

total distance = distance powered + distance coasting

total distance = 56.9 m + 853.7 m

total distance = 910.6 m

Therefore, Sam travels 910.6 meters before he finally coasts to a stop.

An average cyclist travels at a speed of 23 mph. Time (t) = 5.1 hours if she wants to ride 190 kilometers.

The distance traveled in a unit of time is called speed. It refers to a thing's rate of movement. The scalar quantity known as speed is the velocity vector's magnitude. It has no clear direction. A faster rate of movement is indicated by a higher speed. It travels slower if the speed is lower. It has zero speed if it isn't moving at all.

The formula: can be used to determine the constant velocity of an object traveling straight forward.

r = d / t

where

r stands for rate or speed (sometimes denoted as v, for velocity)

d is the traveled distance.

t the amount of time needed to finish the movement

The average speed of an object over a period of time is given by this equation. We can see the object's average speed here, however at some moments over the time frame, it may have been moving faster or slower.

As the time interval gets closer to zero, the maximum average speed is reached. The speed at that moment is what you see when you look at a speedometer in an automobile. While you may have briefly reached a speed of 60 mph, your average speed over the course of 10 minutes could have been much higher or much lower.

190 Km (given)

1 km = 0.621 miles (should know)

So, 190 km = (190x0-621) miles

                  = 118 miles

23 miles per hour means,

23 miles- 1 hour

so, 118 miles - (118 × 1/ 23) hour

118 miles = 5.1 hour.

The beta of stock B needs to be approximately 0.12.

To determine the required beta value for stock B, we need to consider the beta of the portfolio and the beta of stock A. Since the portfolio contains equal amounts of Treasury bills, stock A, and stock B, we can use a weighted average formula to calculate the beta of the portfolio. Given that the beta of the portfolio is 1.04 and the beta of stock A is 1.65, we can calculate the weight of stock B as follows:

(1.04) = (0.5)(1.65) + (0.5)(Beta of stock B)

Solving for the beta of stock B, we find that it needs to be approximately 0.12 to achieve a portfolio beta of 1.04. This means that stock B has a lower systematic risk compared to stock A, making it less sensitive to market fluctuations.

If an aardvark is driving a sailboat, and at the end of his first 50 meters he is traveling 30 m/s. He then uniformly accelerates at 3 m/s2 for 30 seconds, the aardvark has traveled a total distance of 2300 meters after the 30 seconds of acceleration.

There are three equations of motion given by  Newton ,

v = u + at

S = ut + 1/2×a×t²

v² - u² = 2×a×s

As given in the problem, the aardvark is driving a sailboat, and at the end of his first 50 meters, he is traveling 30 m/s. He then uniformly accelerates at 3 m/s2 for 30 seconds.

S = ut + 1/2 ×a×t²

The total kinetic energy before the collision is 0.8 J and the total kinetic energy after the collision is 3.3375 J.

Kinetic energy is the energy of motion. It is the energy an object has due to its motion. Kinetic energy is also known as “dynamic energy” and is equal to the work done on an object to move it at a certain speed. Kinetic energy is a form of energy that is directly proportional to the mass of the object and to the square of its velocity.

The collision between block A and block B is an elastic collision. This means that the total kinetic energy of the two blocks before the collision is equal to the total kinetic energy of the two blocks after the collision.
Before the collision, block A has a kinetic energy of KE = 0.5mv^2 = 0.5 x 0.10 x (4.0)^2 = 0.8 J.
After the collision, block A has a kinetic energy of KE = 0.5mv^2 = 0.5 x 0.10 x (1.5)^2 = 0.3375 J.
Block B has a kinetic energy of KE = 0.5mv^2 = 0.5 x 0.15 x (0)^2 = 0 J before the collision.
After the collision, block B has a kinetic energy of KE = 0.5mv^2 = 0.5 x 0.15 x (4.0)^2 = 3 J.
Therefore, the total kinetic energy before the collision is 0.8 J and the total kinetic energy after the collision is 3.3375 J. Since the total kinetic energy before and after the collision is the same, the collision is elastic.

When dealing with optics, there is an incident wave, a reflected wave, and a transmitted wave. An incident wave is the initial wave coming out from the source, like a flashlight.

Then the reflected wave is created when the incident wave encounters an interface like a piece of glass. The reflected wave will reflect like you would expect.

Then, the transmitted wave is the wave which passes through the interface and continues.

So, a good question would be to ask for the value of the reflected wave function given an initial incident wave.

Another example entirely would be to look at the reflected wave on a tensioned string. If you shake a string up and down, a wave will be sent through it. Once hitting the wall, the wave will reflect back. A good question there is asking how the amplitude of the wave changed.

a) The isocost curve equation is G = (20000 - 100C)/500. b) The isocost curve equation is G = (30000 - 100c)/500. c) The isocost curve equation is G = (20000 - 100C)/375. d)  The isocost curve equation is G = (20000 - 120C)/500.

To draw the isocost curve showing the different combinations of gas and coal, we need to use the cost per unit values for coal and gas, as well as the given expenditure (TC) and the changes in expenditure or prices.

Let's denote the quantity of coal as C and the quantity of gas as G. The cost per unit of coal is 100, and the cost per unit of gas is 500.

(a) Initial expenditure (TC) of 20000:

To find the combinations of gas and coal that can be purchased with an initial expenditure of 20000, we can use the following isocost equation

TC = 100C + 500G

We can rearrange the equation to solve for G in terms of C

G = (TC - 100C) / 500

Now we can plot the isocost curve with TC = 20000 using the equation above.

(b) Expenditure (TC) increases by 50%

If the expenditure increases by 50%, the new expenditure (TC_new) becomes 1.5 × TC = 1.5 × 20000 = 30000.

We can use the same isocost equation as before, but with the new expenditure value:

TC_new = 100C + 500G

Rearranging the equation to solve for G

G = (TC_new - 100C) / 500

Now we can plot the isocost curve with TC_new = 30000.

(c) Gas price reduced by 25%:

If the gas price is reduced by 25%, the new cost per unit of gas (Gas_new) becomes 0.75 × 500 = 375.

We can use the original isocost equation, but with the new cost per unit value:

TC = 100C + 375G

Rearranging the equation to solve for G

G = (TC - 100C) / 375

Now we can plot the isocost curve with the reduced gas price.

(d) Coal price rises by 20%

If the coal price rises by 20%, the new cost per unit of coal (Coal_new) becomes 1.2 × 100 = 120.

We can use the original isocost equation, but with the new cost per unit value:

TC = 120C + 500G

Rearranging the equation to solve for G:

G = (TC - 120C) / 500

Now we can plot the isocost curve with the increased coal price.

By plotting these isocost curves on a graph with G on the y-axis and C on the x-axis, we can visualize the different combinations of gas and coal that can be purchased at the given expenditures or price changes.

The given statement "If you made careful measurements of V vs t for a capacitor C discharging through a resistor R, you should have obtained what is known as an exponential decay curve." is TRUE because when a capacitor discharges through a resistor, the voltage across the capacitor decreases with time.

The relationship between the voltage and time is not linear, but rather follows an exponential decay curve.

This is because the rate of discharge is proportional to the amount of charge remaining on the capacitor, which decreases exponentially with time.

By measuring the voltage at various points in time, we can plot a graph of voltage against time and observe this exponential decay curve.

This curve is a characteristic feature of RC circuits, where R represents the resistance and C represents the capacitance. The time constant of the circuit, which is equal to RC, determines the rate of decay of the voltage.
