The 57.5-gram ball hit her racket with a northward velocity of 26.7 m/s. Upon impact with her 331-gram racket, the ball rebounded in the exact opposite direction (and along the same general trajectory) with a speed of 29.5 m/s. a. Determine the pre-collision momentum of the ball. b. Determine the post-collision momentum of the ball.
