A racquet ball with mass m = 0.23 kg is moving toward the wall at v = 17.3 m/s and at an angle of 0 = 33° 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 = 0.066 s.
