A mass m slides down a fixed plane inclined at an angle a to the horizontal plane after covering the entire length of the inclined plane. The height of the inclined plane is h and the coefficient of friction over both surfaces is `mu`.

A body takes ''n'' times as much time to slide down a rough inclined plane as it takes to slide down an identical but smooth inclined plane. If the angle of inclination of the inclined plane is ''theta'' . What is the coefficient of friction between the body and the rough plane ?

A body takes 1(1/3) times as much time to slide down a rough inclined plane as it takes to slide down an identical bust smooth inclined plane. If the angle of inclination is 45°, find the coefficient of friction.

It takes a block twice as long to slide down a plane incline at 45^(@) to the horizontal as it would take for it to slide down the same plane had the plane been frictionless. Colculate the coefficient of friction between block and inclined plane.
