Kinetic Energy and Momentum: Practice Problem & Solution

If the kinetic energy of a body is increased by 3%, its momentum will increase by :
1 %
1.5 %
3 %
4.5 %

Short Solution (Best for NEET):

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

K = P²/2m so,

∇K/K=2∇P/P

Solving We get , ∇P/P = 1.5%
