Question

A jet shoots a stream of water vertically upward. The water leaves the jet with a velocity $v_{0}$

and at a mass rate R kg/s. A horizontal board with mass m faces the water stream as shown. Water jet strikes the board normally and then bounces off sideways. Assume area of cross-section of water stream, does not change as it goes up.

When board is placed very close to the jet and then released, it stays in equilibrium. What is the value of $m$ ?
