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...
