Find an expression for the work done against friction when a body is made to slide down an inclined plane?

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

Calculate the amount of work done in moving a body up a rough inclined plane .

When body slides down from rest along smooth inclined plane making angle of 45^(@) with the horizontal, it takes time T When the same body slides down from rest along a rough inclined plane making the same angle and through the same distance it is seen to take time pT , where p is some number greater that 1. Calculate late the coefficient of friction beween the body and the rough plane. .

(a) A block slides down an incline of angle 45^(@) with an acceleration (g)/(2 sqrt(2)) . Find the friction coefficient. (b) A block slides down at 45^(@) inclined plane in twice the time it takes to slide down a smooth 45^(@) incline. What is friction co-efficient between the block and the incline? ( c) A block slides down on a rough inclined plane of inclination 30^(@) with constant velocity. If this block is projected up the plane with a velocity of 10 m//s , then at what distance along the inclined plane , the block will come to rest? (d) A body is launched up on a rough inclined plane of inclination theta . If time of ascent is half of time of descent, find the friction coefficient.
