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 ?

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?

A smooth block is released at rest on a 45^(@) incline and then slides a distance d . The time taken to slide is n times as much to slide on rough incline than on a smooth incline. The coefficient of friction is

A smooth block is released at rest on a 45^(@) incline and then slides a distance d . The time taken to slide is n times as much to slide on rough incline than on a smooth incline. The coefficient of friction is

A smooth block is released at rest on a 45^(@) incline and then slides a distance 'd'. The time taken to slide is 'n' times as much to slide on rough incline than on a smooth incline. The coefficient of friction is

A smooth block is released at rest on a 45^(@) incline and then slides a distance d . The time taken to slide is n times as much to slide on rough incline than on a smooth incline. The coefficient of friction is

A block released from rest from the top of a smooth inclined plane of inclination 45^(@) takes time 't' to reach the bottom . The same block released from rest , from top of a rough inclined plane of same inclination , takes time '2t' to reach the bottom , coefficient of friction is :
