A tennis ball initially moves with a velocity of 28.0 m/s horizontally to the right. A tennis racket strikes the ball, giving it a velocity of 28.0 m/s to the left. Treat the collision as elastic and the ball and racket as particles of mass 0.0580 kg and 0.261 kg respectively.
(a) Does the speed of the racket change as a result of the collision?
(b) What is the value of the total momentum of the system?
(c) Find the initial velocity of the racket.
