for coefficient of restituition is CR = sqrt(h/H)
given that h = 0.7 m
and H = 0.8 m
then CR = sqrt(h/H) = sqrt(0.7/0.8) = 0.94

Two identical balls come into a collision with a coefficient of restitution e=0.8. Before the impact, VA = 7 m/s and V3 = 3 m/s. Their directions are as shown. Determine the magnitude of velocity of each ball after the impact. Include the following steps in your VB solution: a) Define a coordinate system appropriately.

please help!
The figure below shows a metal ball with a mass of 2.84 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v - 10.0 ms, and the angle its path makes with the wall is 8 - 60.0° as shown. (Because we are analyzing the motion of the ball over a very short time just before and after Impact, you may safely ignore the effect of gravity on the...

Need help on part C!
As shown, tennis ball A rolls off the top of a 10.0 m high wall, falls 4.00 m, and strikes another tennis ball, B, obliquely. (Figure 1) Before the collision, tennis ball B has a speed of 21.0 m/s as it moves upward. Each ball's mass is 57.0 g and the collision's coefficient of restitution is 0.730. (Figure 2) In the figure, a-30.0° and фі-20.0. What is (VA), , the velocity of tennis ball A,...
