Step 1

In this case, an impulse is acted on the ball, which is the case of the change of momentum of the ball in a short time interval due to a large force acting on it.

The impulse on the ball can be found by the change in the momentum of the ball, as

I=p2-p1p2 

This is the impulse acting on the ball

 

Step 2

The impulse is also defined as the amount of force acting on the ball in a short time interval t.

So, impulse can also be written as

I=Ftt is the time interval for which the force has been acted upon.So, t=IFt=1.115.714t=0.07 st=7×10-2 s

This is the time for which the bat and ball were in contact.
