A particle falls from a height h upon a fixed horizontal plane and rebounds. If e is the coefficient of restitution, the total distance travelled before rebounding has stopped is

• A

  $h\left(\frac{1+e^2}{1-e^2}\right)$

• B

  $h\left(\frac{1-e^2}{1+e^2}\right)$

• C

  $\frac{h}{2}\left(\frac{1-e^2}{1+e^2}\right)$

• D

  $\frac{h}{2}\left(\frac{1+e^2}{1-e^2}\right)$
