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

Solution

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