A block of mass m collides with another block of mass 3m completely inelastically as shown in figure. What is the maximum value of v ( in m//s) for which the block B does not move. Assume that initially spring is in natural length and blocks A and B are at rest. (K//m=100 S.I. unit )

A block of mass m is dropped onto a spring of constant k from a height h . The second end of the spring is attached to a second block of mass M as shown in figure. Find the minimum value of h so that the block M bounces off the ground. If the block of mass m sticks to the spring immediately after it comes into contact with it.

A block of mass m rests on a wedge of mass M which, in trun, rests on a horizontal table, as shown in figure. All surfaces are frictionless. If the system starts at rest with point P of the block a distance h above the table, find the speed of the wedge the instant point P touches the table.

Three blocks are initially placed as shown in the figure. Block A has mass m and initial velocity v to the right. Block B with mass m and block C with mass 4 m are both initially at rest. Neglect friction. All collisions are elastic. The final velocity of block A is
