A small block when released on an inclined plane,it first slides down and then stops after sliding down a height 'h'. This strange behavior is due to the coefficient of friction that is hear proportional to the distance slid by the block. The maximum speed of the block during this motion is `sqrt(gh/n)` .Find 'n' value(Acceleration due to gravity is 'g')
