Problems 1. A penny dropped from a tall building has a speed given by the equation 5m -0.5(s-1 a) How far will the penny have fallen after 4 seconds? b) What is the penny's acceleration after 4 seconds?
A ball is launched from the ground toward a tall wall of a building at initial speed v0 = 24 m/s at an angle of 39 degrees relative to the horizontal. The wall is at a distance of 32 m from the launch point. How far above the launch point does the ball hit the wall? Your answer should be in meters, but enter only the numerical part in the answer box.

A tennis ball is dropped from the top of a tall building of height H. It takes time t for the ball to reach the ground. At t/2 the ball has fallen through a distance: [a] equal to H/2 [b] less than H/2 [c] more than H/2.
A 2 kg stone is dropped from a 50-m-tall building. Simultaneously, a second 1 kg stone is thrown horizontally from the building at a speed of 14 m/s , as shown in the figure. (Figure 1) Part A: Calculate the x position of the center of mass of the two-stone system the moment after they are set in motion. Express your answer in meters as an integer. Part B: Calculate the y position of the center of mass of the...

A 0.5 kg steel ball is attached to a very light string and hung from the ceiling. The string is 0.78 meters long. The ball is given a horizontal push. The speed after this quick push is 1.4 m/s. The ball then swings like a pendulum. At its highest point, what angle does the string make with the vertical axis? (10 points + 5 extra credit)
please explain the answer 2) A ball is dropped from rest at a height H. At height h (below H) the ball bounces off a surface with no loss in speed. The surface is tilted at 45°, so the ball bounces off horizon- tally. Derive an expression for the distance the ball travels in the horizontal direction. Plot the distance traveled in the horizontal direction as a function of h where h varies between O and H. 3) Imagine an...
A ball is launched from the ground toward a tall wall of a building at initial speed v0 = 21 m/s at an angle of 42 degrees relative to the horizontal. The wall is at a distance of 29 m from the launch point. What is the magnitude of the ball's velocity vector as it hits the wall? Your answer should be in m/s, but enter only the numerical part in the answer box.
