In a little league baseball game, the 145 g ball enters the strike zone with a speed of 14.0m/s . the batter hits the ball, and it leaves his bat with a speed of 23.0m/s in exactly the opposite direction. what is the magnitude of the impulse delivered by the bat to the ball? if the bat is in contact with the ball for 1.0ms , what is the magnitude of the average force exerted by the bat on the ball?

5365 N

Explanation:

v = Final velocity = 23 m/s

u = Initial velocity = -14 m/s (opposite direction)

m = Mass of ball = 145 g

t = Time taken = 1 ms

Impulse is given by

Impulse is also given by

The magnitude of the average force exerted by the bat on the ball is 5365 N
