A block is connected to a relaxed spring and kept on a smooth floor. The block is given a velocity towards the right. Just after this,

two blocks of masses m and 2m are connected by a relaxed spring with a force contant k. the block on the left is given a sharp irnpulse "J" towards the right , and the blocks begin to slide along the table ,(see fig 4E.3) find the maximum compression in the spring .

The two blocks A and B of same mass connected to a spring and placed on a smooth surface. They are given velocities (as shown in the figure) when the spring is in its natural length :

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 shows two identical blocks each of mass m kept on a smooth floor. Block A is connected to front wall with a just taut straight string and block B is connected to rear wall with a relaxed spring. Assume that the floor of the train car is smooth and exerts no horizontal forces on the blocks. Mark the correct statement(s).
