A block is sliding down on an inclined plane of slope $\displaystyle \theta$ and at an instant $\displaystyle t=0$ this block is given an upward momentum so that it starts moving up on the inclined surface with velocity $\displaystyle u$. The distance $\displaystyle (S)$ travelled by the block before its velocity become zero, is $\displaystyle \_\_\_\_$. ( $\displaystyle g=$ gravitational acceleration)
