A block is released at A and slides on smooth surface in shape of quarter circel. The horizontal part is rough if the block comes to rest 1.0 m away from B, then what is the coefficient of kinetic friction?

In the track shown in figure section AB is a quadrant of a circle of 1 meter radius. A block is released at A and slides without friction until it reaches B . After B it moves on a rough horizontal floor and comes to rest at distance 3 meters from B. What is the coefficient of friction between floor and body?

A body freely released from A slides down a smooth inclined plane 'AB' and then a rough incline plane 'BC' such that BC = N (AB). If the block comes to rest at C, then coefficient of kinetic friction between the block and inclined plane is?

A block of mass m is released on the top of a smooth inclined plane of length x and inclination theta as shown in figure. Horizontal surface is rough. If block comes to rest after moving a distabce d on the horizontal surface, then coefficient of friction between block and surface is :-
