If the momentum of a body is increased by 100 % , then the percentage increase in the kinetic energy is

Options

  1. A150 %
  2. B200 %
  3. C225 %
  4. D300 %

Correct answer

D. 300 %

Step-by-step solution

KE = p^2 2 m KE ₂= KE ₁ ( p₂ p₁ )^2= KE ₁ ( 2 p p )^2 aligned KE ₂ & =4 KE ₁ & = KE ₁+3 KE ₁= KE ₁+300 % of KE ₁ aligned
