A steel ball strikes a fixed smooth steel plate placed on a horizontal surface atan angle `theta` with the vertical. If the coefficient of restitution is e, the angle at which the rebound will take place is:

`theta`

`tan^(-1) [ ( tan theta )/( e ) ]`

`e tan theta`

`tan^(-1) [( e )/( tan theta )]`
