For shown situation, if collision between block A and B is perfectly elastic, then find the maximum energy stored in spring in joules.

In a perfectly elastic collision between two bodies

The friction coefficient between the horizontal surface and each of the block shown in the figure is 0.2 . The collision between the blocks is perfectly elastic. Find the separation between them when they come to rest. (Take g=10m//s^2 ).

The track shown in figure is frictionless. The block B of mass 2 m is lying at rest and the block A of mass m is placed along the track with some speed. The collision between A and B is perfectly elastic. With what velocity should the block A be started to get the sleeping man awakened ?

Three blocks of masses m , m and M are kept on a frictionless floor as shown in the figure .The leftmost block is given velocity v towards the right . All the collision between the blocks are perfectly inelastic . The loss in kinetic energy after all the collision is 5//6th of initial kinetic energy. The ratio of M//m will be

Figure shown a block P of mass m resting on a smooth horizontal surface, attached to a spring of force constant k which is rigidly fixed on the wall on left side, shown in the figure . At a distance l to the right of the block there is a rigid wall. If block is pushed towards loft so that spring is comparessed by a distance 5l//3 and when released, if will starts its oscillations. If collision of block with the wall is consdered to be perfectly elastic. Find the time period of oscillation of the block.

At a distance l to the right of the block there is a rigid wall. If block is pushed towards left so that spring is compressed by a distance 5l//3 and when released, if will starts its oscillations. If collision of block with the wall is considered to be perfectly elastic. Find the time period of oscillation of the block.
