Given a billiard ball hits a fixed horizontal surface with a velocity v = 32 m/s at an angle of 60 degrees with the horizontal Further, the coefficient of restitution is given to be 0.8. Find the magnitude of the rebound velocity v in m/s. 60°
pong ball has a mass of 2.0 g. The coefficient of restitution for the collision of the ball th the table e - 0.80 and assume that the table surface is frictionless and does not move. If it is uck with the initial velocity shown, determine a. [6/8] the velocity of the ball just after the first rebound. b. [2/8] the velocity of the ball just after the second rebound. 0.92 m pong ball has a mass of 2.0 g....
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 Bhas a speed of 19.0 m/s as it moves upward. Each ball's mass is 57.0 g and the collision's coefficient of restitution is 0.630.(Figure 2) In the figure, ?1=30.0? and?1=20.0?. What is (vA)1, the velocity of tennis ball A, immediately before the collision?

You throw a 0.350 kg tennis ball horizontally toward a wall. The speed of the ball is 12 m/s before it hits the wall, and it bounces back with the same speed of 12 m/s. If the ball remains in contact with the wall during this collision for 0.025 s, what is the magnitude of the average force exerted on the ball?
