A tennis ball initially moves with a velocity of 28.0 m/s horizontally to the right. A tennisracket strikes the ball, giving it a velocity of 28.0 m/s to the left. Treat the collision aselastic and the ball and racket as particles ofmass 0.0580 kgand 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.
