Starting from rest, the time taken by a body sliding down on a rough inclined plane at `45^(@)` with the horizontal is twice the time taken to travel on a smooth plane of same inclination and same distance. Then, the coefficient of kinetic friction is

A piece of ice slides down a rough inclined plane at 45^(@) inclination in twice the time that it takes to slide down an identical but frictionless inclined plane. What is the coefficient of friction between ice and incline ?

The time taken by a body to slide down a rough 45^(@) inclined plane is twice that required to slide down a smooth 45^(@) inclined plane. The coefficient of kinetic friction between the object and rough plane is given by

The time taken by a body to slide down a rough 45^(@) inclined plane is twice that required to slide down a smooth 45^(@) inclined plane. The coefficient of kinetic friction between the object and rough plane is given by

Time taken by a body to slide down a smooth plane of inclination 45^(@) is two-third the time taken to slide down a similar but rough plane. What is the coefficient of sliding friction between the body and the inclined plane?

The time taken for an ice block to slide down on inclined surface of inclination 60^(@) is 1-2 times the time taken by the same ice block to slide down a frictionless inclined plane of the same inclination. Calculate the coefficient of friction between ice and the inclined plane ?
