Kinetic Energy and Momentum: Practice Problem & Solution

If the kinetic energy of a body is increased by 300%, its momentum will increase by :
100%
150%
200%
400%

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:

Relation between Kinetic Energy and Momentum is

P = √(2mK)

When kinetic energy is increased by 300 % it becomes 4K so new momentum is

P1= √(2m.4K) =2P
