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 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.
