In a Little League baseball game, the 145g ball enters the strikezone with a speed of 15.0 m/s. The batter hits the ball, and itleaves his bat with a speed of 20.0 m/s in exactly the oppositedirection.
What is the magnitude of the impulse delivered by the bat to theball?
If the bat is in contact with the ball for 1.5m/s. what is themagnitude of the average force exerted by the bat on the ball?

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 hat. 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.
