A pitcher throws a 0.14-kg baseball toward the batter so
that it crosses home plate horizontally and has a speed of 42 m/s
just before it makes contact with the bat. The batter then hits the
ball straight back at the pitcher with a speed of 48 m/s. Assume
the ball travels along the same line leaving the bat as it followed
before contacting the bat. (a) What is the magnitude of the
impulse delivered by the bat to the baseball? (b) If the ball is in
contact with the bat for 0.005 0 s, what is the magnitude of the
average force exerted by the bat on the ball? (c) How does your
answer to part (b) compare to the weight of the ball?
