A block of weight 4 kg is resting on a smooth horizontal plane. If it is struck by a jet of water at the rate of 2 kg s^(-1) and at the speed of 10 m s', then the initial acceleration of the block is

A block of mass 5 kg is initially at rest on a rough horizontal surface. A force of 45 N acts over a distance of 2 m . The force of friction acting on the block is 25 N . The final kinetic energy of the block is

Two blocks of masses 1 kg and 2 kg are placed in contact on a smooth horizontal surface as shown in fig. A horizontal force of 6N is applied d(a) on a 1-kg block. Find the force of interaction of the blocks. .
