3. The impulse necessary to change the momentum of an object by 5
kgm/s is:

Impulse, J = 5 kg-m/s

Explanation:

Accoding to impulse-momentum theorem, the change in momentum of an object is equal to the impulse applied to it. In this problem, the change in momentum of an object is 5 kg-m/s.

We need to find the impulse necessary to change the momentum. So, impulse will be equal to 5 kg-m/s.
