1-What is the magnitude of the initial momentum of the racquet ball?

2- What is the magnitude of the change in momentum of the racquet ball?

3-What is the magnitude of the average force the wall exerts on the racquet ball?

4- Now the racquet ball is moving straight toward the wall at a velocity of v_i = 18.5 m/s. The ball makes an inelastic collision with the solid wall and leaves the wall in the opposite direction at v_f = -12.4 m/s. The ball exerts the same average force on the ball as before.

What is the magnitude of the change in momentum of the racquet ball?

5-What is the time the ball is in contact with the wall?

6-What is the change in kinetic energy of the racquet ball?

Ball Hits Wall 1 2 3 4 5 6 7 0 A racquet ball with mass m = 0.233 kg is moving toward the wall at v = 18.5 m/s and at an angle of 0 = 26° 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 = 0.071 s.
