Expert Solution
Step 1

IMPULSE:- 

We know that the impulse is defined as the force and change in time. 

Impulse = Ftwhere F is the force t is the change in time 

We also can say that the change in momentum is defined as the impulse. the term "impulse" is used to explain or measure the effect of a force working overtime time to modify an object's momentum. It is denoted by the letter J and is usually measured in Newton seconds or kilograms per second.
