The time taken by a block of wood (initially at rest) to slide down a smooth inclined plane 9.8 m long (angle of inclination is `30^(@)`) is

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.

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 but smooth inclined plane,If the angle of inclination is 45^(@) find the coefficient of friction.

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 ?
