A ball falls from a height $h$ upon a fixed horizontal floor. The co-efficient of restitution for the collision between the ball and the floor is 'e'. The total distance covered by the ball before coming to rest is [neglect the air resistance]

• A

  $\frac{1-\mathrm{e}^2}{1+\mathrm{e}^2} \mathrm{~h}$
• Correct answer
  B

  $\frac{1+e^2}{1-e^2} h$
• C

  $\frac{1-2 e^2}{1+e^2} h$
• D

  $\frac{1+2 e^2}{1-e^2} h$

Hence, the correct answer is option: 'B'.
