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:

I=8 Nw.s

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

[tex]I=\Delta p=m(v_2-v_1)=F.t[/tex]

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

[tex]I=(400) (0.02)=8\ Nw.s[/tex]

[tex]\boxed{I=8\ Nw.s}[/tex]
