A body falls freely from a height of 100 ~m on to the ground and rebounds to a maximum height of 36 ~m after collision. The coefficient of restitution between ground and the body is

Options

  1. A0.4
  2. B0.36
  3. C0.6
  4. D0.5

Correct answer

C. 0.6

Step-by-step solution

First height of rebound, h₁=e^2 h₀ 36= e ^2(100) e ^2= 36 100 e = 36 100 = 6 10 =0.6
