A 0.057 kg tennis ball and a tennis racket collide. The racket has an initial momentum of -2.80 kg•m/s and a final momentum of -1.97 kg•m/s. The ball has an initial momentum of 0.02565 kg•m/s. If you assume the collision is elastic, what is the final velocity of the ball?
A. -4.75 m/s
B. -83.27 m/s
C. -0.80 m/s
D. -14.11 m/s
