A body takes time `t` to reach the bottom oa a smooth inclined plane of angle `theta` with the horizontal. If the plane is made rought, time taken now is `2t`.The coefficient of friction of the rough surface is

If the body starts from rest from the top of the rough inclined plane of length 1, time taken to reach the bottom of the plane is

A body is pushed up on a rough inclined plane making an angle 30^(@) to the horizontal. If its time of ascent on the plane is half the time of its descent. Find coefficient of friction between the body and the inclined plane.

A body is pushed up on a rough inclined plane making an angle 30^@ to the horizontal. If its time of ascent on the plane is half the time of its descent, find coefficient of friction between the body and the incined plane.

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 ?
