A bomb of mass 3 m is kept inside a closed box of mass 3 m and length 4 l at its centre. It explodes in two parts of mass m and 2m. The two parts move in the opposite directions and stick to the opposite sides of the walls of the box. The box is kept on a smooth horizontal surface. What is the distance moves by the box during this time interval.

Two identical carts constrained to move on a straight line, on which sit two twins of same mass, are moving with equal velocity. At some time snow begins to drop uniformly. Ram, sitting on one of the carts, picks the snow from cart and throws off the falling snow sideways and in the second cart Shyam is asleep.
