Question

A force acting on a body of mass 3.0kg changes its velocity from 12ms-1 to 15ms-1 calculate the impulse the force delivers to the body

Answer 1

Answer:

9 Ns

Explanation:

As you probably know, impulse imparted =Ft= m(v-u)

So, putting the values in the formula, impulse=3(15-12)

                                                                           =9Ns
