Question

a baseball bat is in contact with a ball for 0.02 seconds, and exerts a force of 400 newtons. what is the impulse on the ball?​

Answer 1

I=8 Nw.s

Step-by-step explanation:

Impulse

It is a physical magnitude that measures the force applied to an object by the time that force is acting. It produces a change in the momentum of the object, which is expressed in the following formula

`I=\Delta p=m(v_2-v_1)=F.t`

We know the bat applies a force on the ball of F=400 N during t=0.02 sec, thus the impulse is

`I=(400) (0.02)=8\ Nw.s`

`\boxed{I=8\ Nw.s}`
