Linear Momentum and Second Law of Motion: Practice Problem & Solution

A body moving with uniform velocity is stopped in 0.25 sec by applying a force of 200 N. What is the impulse :
5 N-s
25 N-s
50 N-s
100 N-s

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Linear Momentum and Second Law of Motion. Understanding the underlying formula is key to arriving at the correct answer below:

Impulse is change in momentum so, J = F.dt = 200 × 0.25 =50 N-s
