Let F be the magnitude of the force needed to keep the box sliding at constant speed, and f the magnitude of kinetic friction. Then by Newton's second law, the net horizontal force on the crate is

F - f = 0

so that

F = f

f is proportional to the magnitude of the normal force n,

f = 0.38n

The net vertical force is

n - mg = 0

which tells us that

n = mg = (29 kg) (9.8 m/s²) ≈ 284 N

Then the required force must have magnitude

F = f = 0.38 (284 N) ≈ 110 N

From a position on the ground, a ball is thrown 36 m/s vertically upward. The speed of the falling ball is given by v = -9.8 (m/s2) t j.

The ball is going upward, even if its upward motion is occurring at a lower velocity. In light of this, the ball's velocity is also positive. The gravitational force is what causes the acceleration that the body experiences. From the top of a multi-story building, a ball is hurled vertically and at a speed of 20 meters per second. The ball is thrown from a location that is 25 meters above the ground in height.

The greatest height of the ball can be calculated using the vertical motion model, h=-16t2 + vt+s, where v is the initial velocity in feet/second and s is the height in feet. From the top of a multi-story building, a ball is hurled vertically and at a speed of 20 meters per second.

The statement that is true about the theory of plate tectonics and the theory of continental drift C. The theory of plate tectonics gives the method by which continents can move as part of plates .

According to the scientific hypothesis of plate tectonics, the underground movements of the Earth create the primary landforms. By explaining a wide range of phenomena, including as mountain-building events, volcanoes, and earthquakes, the theory, which became firmly established in the 1960s, revolutionized the earth sciences.

The scientist Alfred Wegener is most closely connected with the concept of continental drift. Wegener wrote a paper outlining his notion that the continents were "drifting" across the Earth, occasionally crashing through oceans and into one another, in the early 20th century.

According to tectonic theory, the Earth's surface is dynamic and can move up to 1-2 inches every year. The numerous tectonic plates constantly move and interact. The outer layer of the Earth is altered by this motion. The result is earthquakes, volcanoes, and mountains.

The rank of the forces in order of increasing magnitude is Fg < FB < FA.

option D is the correct answer.

The net force on an elevator moving upwards is determined by the force of gravity acting downwards and the normal force of the elevator acting upwards.

That is, the two forces acting on a person when he is moving in an elevator are:

When the two forces are of equal magnitude, the elevator will be static or moving with constant velocity.

When the magnitude of the two force are unequal, then the elevator will be accelerating upward or downward.

Since the elevator is moving upwards, it implies that the normal force is greater than the force of gravity acting downwards.

The box at the bottom will feel much heavier due to the weight of box and gravity acting downwards.

FA = FB + Fg

The wavelength has not changed because the tension in the wire is proportional to the weight of the hanging object, and the wave speed depends only on the tension and the linear mass density of the string.

To calculate the change in wavelength of the third harmonic caused by replacing the light ball with the heavy one, we can use the equation for the wavelength of a standing wave on a string:

λ = 2L/n

where λ is the wavelength, L is the length of the string, and n is the harmonic number.

For the third harmonic, n = 3, so the original wavelength is:

λ₁ = 2(1.10 m)/3

λ₁ = 0.733 m

To find the tension in the wire with the original ball, we can use the formula:

F = mg + T

where F is the tension in the wire, m is the mass of the ball, g is the acceleration due to gravity, and T is the tension due to the wire itself.

Solving for T, we get:

T = F - mg

T = 110.0 N - (0.110 kg)(9.81 m/s²)

T = 108.82 N

Now that we have the tension, we can use the formula for the wave speed on a string:

v = √(F/μ)

where v is the wave speed, F is the tension, and μ is the linear mass density of the string.

The linear mass density can be found using the formula:

μ = m/LA

where m is the mass of the wire, L is the length of the wire, and A is the cross-sectional area of the wire.

μ = (π/4)(0.001024 m)²(1.10 m)/(0.018 kg/m³)

μ = 1.41×10⁻⁶ kg/m

Now we can find the wave speed:

v₁ = √(108.82 N/1.41×10⁻⁶ kg/m)

v₁ = 296.48 m/s

Using the equation for the wavelength of a standing wave on a string, we can find the new wavelength with the heavier ball:

λ₂ = 2L/n = 2(1.10 m)/3 = 0.733 m

The wavelength has not changed because the tension in the wire is proportional to the weight of the hanging object, and the wave speed depends only on the tension and the linear mass density of the string. Therefore, the change in the weight of the ball does not affect the wave speed or the wavelength.

A wall less than or equal to 14.7 m in height is the highest the player can clear.

Use the kinematic equations of motion to solve the problem. First, we can find the time it takes for the ball to travel 99.1 m horizontally:

d = vt

t = d / v

t = 99.1 m / 36.2 m/s

t ≈ 2.74 s

Now, use the vertical motion equation to find the maximum height the ball reaches:

y = yo + vot + (1/2)at²

where:

yo = 0.996 m (initial height)

vo = v sinθ = 36.2 m/s x sin(30°) ≈ 18.1 m/s (initial vertical velocity)

a = -9.81 m/s² (acceleration due to gravity, pointing downward)

t = 2.74 s (time of flight)

y = 0.996 m + 18.1 m/s x 2.74 s + (1/2) x (-9.81 m/s²) x (2.74 s)²

y ≈ 14.7 m

If a 5kg mass starts from rest at xo = -1 and moves under the action of a variable force F(x) = √1-x² to point xf = 1. Then the total work done by the force is equal to π/2 + 1.

To calculate the total work done by the force in this scenario, we can use the formula for work:

Work = ∫F(x) dx

where F(x) is the force as a function of position and dx represents an infinitesimal displacement.

In this case, the force is given by F(x) = √(1 - x²), and we need to find the total work done as the object moves from xo = -1 to xf = 1.

Let's break down the calculation step by step:

Write the integral for work:

Work = ∫F(x) dx

Substitute the given force:

Work = ∫√(1 - x²) dx

Integrate with respect to x:

To integrate the square root of (1 - x²), we use the trigonometric substitution. Let's substitute x = sin(θ) and dx = cos(θ) dθ.

Work = ∫√(1 - sin²(θ)) cos(θ) dθ

Simplify the integrand:

Using the trigonometric identity sin²(θ) + cos²(θ) = 1, we can rewrite the integrand as cos²(θ).

Work = ∫cos²(θ) dθ

Apply the power-reducing formula:

The power-reducing formula states that cos²(θ) = (1 + cos(2θ)) / 2. We can use this formula to simplify the integrand further.

Work = ∫(1 + cos(2θ))/2 dθ

Integrate the terms separately:

Work = (1/2) ∫dθ + (1/2) ∫cos(2θ) dθ

The first integral, ∫dθ, is simply θ, and the second integral, ∫cos(2θ) dθ, can be calculated as sin(2θ)/2.

Work = (1/2) θ + (1/2) (sin(2θ)/2) + C

Evaluate the integral limits:

To find the total work done, we need to evaluate the integral at the upper and lower limits of integration.

At xf = 1, the angle θ is π/2, and at xo = -1, the angle θ is -π/2.

Work = (1/2) (π/2) + (1/2) (sin(2(π/2))/2) - [(1/2) (-π/2) + (1/2) (sin(2(-π/2))/2)]

Simplifying further:

Work = π/4 + (1/2) - (-π/4 + (1/2))

Work = π/4 + 1/2 + π/4 + 1/2

Work = π/2 + 1

Therefore, the total work done by the force is equal to π/2 + 1.

The horizontal and vertical distances are x = 210 m and y = -240.35 m, respectively.

Explanation:

Using the equation of the displacement in the x-direction, we have:

(let's recall we have a constant velocity in this direction)

\(x=v_{ix}t\)

Where:

\(x=30(7)\)    

\(x=210\: m\)    

Now, we need to use the equation of the displacement in the y-direction to find the vertical distance. Here we have an acceleration (g)

\(y=v_{iy}t-\frac{1}{2}gt^2\)

Where:

Then, the vertical position at 7 s is:

\(y=-\frac{1}{2}(9.81)(7)^2\)

\(y=-240.35\: m\)

Therefore, the horizontal and vertical distances are x = 210 m and y = -240.35 m, respectively. The minus sign means the negative value in the y-direction.
