On a frictionless surface a block of mass. M moving at a speed v collides elastically with another block of same mass M which is initially at rest. After collision the first block moves at an angle theta to its initial direction and has a speed v/3 . The second block’s speed after the collision is :

A force F is applied on a block of mass M . The block is displaced through a distance d in the direction of the force. What is the work done by the force on the block? Does the internal energy change because of this work?
