Question

Upon hitting a bat, a baseball has a change in momentum of 16.5 kg-ms. What is the average

force applied to the baseball the time of impact is 0.00200 seconds?

Answer 1

The average force applied to the baseball is 8.25kN

Explanation:

This problem bothers on the impulse of a force

We know that the change in momentum is expressed as

Ft= mv-mu

Given

Ft=16.5 kg-ms

Time t of impact =0.00200s

The force applied can be solved for

By making F subject of formula

F= (mv-mu)/t

F=16.5/0.002

F= 8250N

F= 8.25kN
