Two ramp (1) and (2) are initially just touching each other and placed on a smooth horizontal surface A block released from the top of ramp (1) when it reaches to the other ramp (2) then the height attained by the block is -

A smooth wedge of mass M rests on a smooth horizontal surface. A block of mass m is projected from its lowermost point with velocity v_(0) . What is the maximum height reached by the block?

Figure shows a block A of mass 6 m having a smooth semicircular groove of radius a placed on a smooth horizontal surface. A block B of mass m is released from a position in groove where its radius is horizontal. Find the speed of the bigger block when the smaller block reaches its bottom most position.

Two blocks of masses m_(1) and m_(2) are connected by an ideal sprit, of force constant k . The blocks are placed on smooth horizontal surface. A horizontal force F acts on the block m_(1) . Initially spring is relaxed, both the blocks are at rest. What is acceleration of centre of mass of system at the instant of maximum elongation of spring

Two blocks of masses m_(1) and m_(2) are connected by an ideal sprit, of force constant k . The blocks are placed on smooth horizontal surface. A horizontal force F acts on the block m_(1) . Initially spring is relaxed, both the blocks are at rest. Which of the following statement is not true tn the watt of above system.

Consider a large block placed on a smooth horizontal surface, with a man standing at one end of the block. The man walks to the other end, relative to the block. The distances (absolute) moved by the man and the block are :

A block of mass m is released from a height R on the frictionless incline as shown. The incline leads to a circle of radius R/2. The maximum height attained by the block is

Two blocks each of mass m are placed on a smooth horizontal surface.They attract each other with a force F=(k)/(r) where r is the separation between them.Calculate work required to increase the separation between the blocks slowly from a to 2a.

Two blocks of mass 2 kg and 4 kg are kept in contact with each other on a smooth horizontal surface. A horizontal force of 12 N is applied on the first block due to which they move with certain constant acceleration. Calculate the force between the blocks.

A block is released from the top of the smooth inclined plane of height h . Find the speed of the block as it reaches the bottom of the plane.
