A block slides down on an icy hill of height h (as shown in Fig ) and stops after covering a distance CB. The distance AB is equal to S. The coefficient of friction μ between the block and ice surface (inclined and horizontal) is

A block slides with a velocity of 10 m/sec. on a rough horizontal surface. It comes to rest after covering of 50 m. If g is 10 m/ sec^(2) , then the coefficient of dynamic friction between the block and surface is

A block of mass m takes time t to slide down on a smooth inclined plane of angle of inclination theta and height h. If same block slids down on a rough inclined plane of same angle of inclination and same height and takes time n times of initial value, then coefficient friction between block and inclined plane is

A block of mass 10 kg slides down on an incline 5 m long and 3 m high. A man pushes up on the ice block parallel to the incline so that it slides down at constant speed. The coefficient of friction between the ice and the incline is 0.1. Find : (a) the work done by the man on the block. (b) the work done by gravity on the block. (c) the work done by the surface on the block. (d) the work done by the resultant forces on the block. (e) the change in K.E. of the block.

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 :-

Starting from rest , a body slides down at 45^(@) inclined plane in twice the time it takes to slide down the same distance in the absence of friction. The coefficient of friction between the body and the inclined plane is

Starting from rest, a body slides down a 45^(@) inclined plane in twice the time it itakes to slide the same distance in the absence of friction. They the coefficient of friction between the body and the inclined plane is

A block slides on ice with a velocity of 5m//s comes to rest after moving through a distance of 13.5m . Find the coefficient of friction ?

A block sliding down a rough 45° inclined plane has half the velocity it would have had, the inclined plane been smooth. The coefficient of sliding friction between block and the inclined plane is

A block slides down an inclined surface of inclination 30^0 with the horizontal. Starting from rest it covers 8 m in the first two seconds. Find the coefficietn of kinetic friction between the two.

A block of mass 5 kg rests on a inclined plane at an angle of 30^(@) with the horizontal. If the block just begins to slide, then what is the coefficient of static friction between the block and the surface?
