A block of mass m_(1) =2 kg slides along a firictionless table with a speed of 10m // s. Directly infront of it,and moving in the same direction is a block of mass m_(2) 5 kg moving at 3 m // s. A mass less spring with a spring constant 11.2 N // cm is attached to as shown in figure-5.146. When the block collide,what is the maximum compression of the spring ? Assume that the spring does not bend.

A block A of mass 2 kg is moving to right with a speed of 5 m/s on a horizontal smooth surface. Another block B of mass 2 kg, with a mass less spring of force constant K =200 N/m attached to it, is moving to left on the same surface with a speed of 3 m/s. Block A collides with the spring attached to B. Calculate (a) the final velocity of the block A. (b) the minimum kinetic energy of the system of two blocks during subsequent motion. (c) Repeat part (b) if there is no spring and the two blocks collide head on. Assume that the blocks are made of perfectly elastic material

A block of mass m is connect to another block of mass M by a massless spring of spring constant k. The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is upstretched when a constant force F starts acting on the block of mass M to pull it. Find the maximum extension of the spring.
