A bullet of mass m moving with velocity u on smooth surface strikes a block of mass M kept at rest. The collision is completely inelastic. Find the common velocity and the fractional loss in kinetic energy.

A block of mass m initially at rest is dropped from a height h on to a spring of force constant k . the maximum compression in the spring is x then

Two blocks 1 and 2 of masses m and 2m respectively are connected by a spring of force constant k. The masses are moving to the right with uniform velocity v each, the heavier mass, leading the lighter one. The spring is of natural length in the motion. Block 2 collides head on with a third block 3 of mass m, at rest, the collision being completely inelastic. Determine the velocity of blocks at the instant of maximum compression of the spring.
