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.
