A block of mass M slides down a rough inclined surface of inclination theta and reaches the bottom at speed at 'v' . However , if it slides down a smooth inclined surface of same length and same inclination , it reaches the bottom with the speed kv. Coefficient of friction between the block and the rough incline is :

(i) There is a vertical loop of radius R. A small block of mass m is slowly pushed along the loop from bottom to a point at height h. Find the work done by the external agent if the coefficient of friction is mu . Assume that the external agent pushes tangentially along the path. (ii) A block of mass m slides down a smooth slope of height h, starting from rest. The lower part of the track is horizontal. In the beginning the block has potential energy U = mgh which gets converted into kinetic energy at the bottom. The velocity at bottom is v=sqrt(2gh) . Now assume that an observer moving horizontally with velocity v=sqrt(2gh) towards right observes the sliding block. She finds that initial energy of the block is E=mgh+1/2 mv^(2) and the final energy of the block when it reaches the bottom of the track is zero. Where did the energy disappear?

A block of mass m slides down a wedge of mass M as shown . The whole system is at rest , when the height of the block is h above the ground. The wedge surface is smooth and gradually flattens.

A small block slides down from the top of hemisphere of radius R = 3 m as shown in the figure. The height 'h' at which the block will lose contact with the surface of the sphere is __________ m. (Assume there is no friction between the block and the hemisphere)
