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]
