A block of mass m is moving with a speed v on a horizontal rought surface and collides with a horizontal monted spring of spring constant k as shown in the figure .The coefficient of friction between the block and the floor is mu The maximum cobnpression of the spring is

Two block of same mass'm' are joined with an dideal spring of spring constant k and sept on a rough surface as shown in figure. The spring is initially unstretched and coefficient of friction between the blocks and horizontal surface is mu and 2 mu respectively. What should be the maximum speed of block 'A' such that the block 'B' does not move ?

A small block of mass 'm' is placed on a plank of mass 'M'. The block is connected to plank with the help of a light string passing over a light smooth pulley as shown in figure. The co-efficient of static friction between the block and plank is mu . The co-efficient of friction between the plank and the horizontal surface is zero. What maximum horizontal force F applied on the block of mass m can make the block and plank not to slide relatively?
