A 0.180 kg billiard ball that is moving at 3.10 m/s strikes the bumper of a pool table and bounces straight back at 2.48 m/s (80% of its original speed). The collision lasts 0.0220 s. (Assume that the ball moves in the positive direction initially.) (a) Calculate the average force (in N) exerted on the ball by the bumper. (Indicate the direction with the sign of your answer.) (b) How much kinetic energy in joules is lost during the collision?...

A racquet ball with mass m = 0.252 kg is moving toward the wall at v = 18.2 m/s and at an angle of θ = 25° with respect to the horizontal. The ball makes a perfectly elastic collision with the solid, frictionless wall and rebounds at the same angle with respect to the horizontal. The ball is in contact with the wall for t = 0.06 s. 1) What is the magnitude of the initial momentum of the racquet...
A bouncy, elastic ball of mass 1.20 kg moving with v = 5.70 m/s hits the wall at an angle of 30° and bounces off. If the collision lasted for 0.01 s, what is the average force exerted by the wall on the ball?
