A man is standing on a cart of mass double the mass of the man. Initially car is at rest on the smooth ground. Now man jumps with relative velocity `'v'` horizontaly towards right with respect to cart. Find the work done by man during the process of jumping.

Two boys each of mass 40 kg are standing on the right side of a trolley of mass 80 kg , initially at rest on smooth floor. The boys jumps to the right with velocity 3 m//s with respect to the trolley before the jump. Find the final velocity of the trolley if the jumps : (a) together , (b) one after the other and (c ) one boy is on the left and the other on the right , the boy on the left jumps to the left and then the boy on the right jumps to the right. Each boy jumps with 3 m//s with respect to the trolley before the jump.

An 80 kg man is riding on a 40 kg cart travelling at a speed of 2.5 m//s on a frictionless horizontal plane jumps off the cart, such that, his velocity just after is zero with respect to ground. The work done by him on th esystem during his jump is given as (A)/(4) KJ (Ain integer). Find the value of A.
