A body with zero initial velocity slips from the top of an inclined plane forming an angle alpha with the horizontal. The coefficient of friction mu between the body and the plane increases with the distance s from the top according to the law mu = bs . After what distance the body will stop.

A small body was launched up an inclined plane set at an angle alpha=15^@ against the horizontal. Find the coefficient of friction, if the time of the ascent of the body is eta=2.0 times less than the time of its descent.

A block sliding down on an inclined plane forms an angle theta with the horizontal. The friction coefficient depends on the distance x covered as mu = kx , where k is a constant. Find the distance covered by the block till it stops and its maximum velocity over this distance. Also , sketch a graph between square of velocity and distance covered x .
