Question

A particle falls from a height h on a fixed horizontal plate and rebounds. If e is the coefficient of restitution, the total distance travelled by the particle before it stops rebounding is

Moderate
Solution

The total distance traveled is

     S=h+2e2h+2e4h+2e6h+=h+2he2+e4+e6+=h+2he21e2=h1+2e21e2=h1+e21e2

Hence the correct choice is (1).
