Subtopic: Kinetic Energy and Momentum

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

Solution:

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
