Problem Set NL16, Question 4:
Felix is the catcher for the South baseball team. In last night's practice, the 0.152-kg baseball moving at 29.3 m/s strikes his glove. Felix naturally recoils the glove a distance of 12.19 cm as he brings the ball to a resting position.
a. Calculate the acceleration of the baseball.
b. What is the average force (in Newtons) applied on the ball by the glove?
c. What is the average force (in Newtons) applied on the glove by the ball?
