A trolley filled with sand moves on a smooth horizontal surface with an initial velocity v. A small hole is there at the base of trolley, from which sand is leaking out at constant rate. As the sand leaks out

The figure shows a man of mass m standing at the end A of a trolley of maas M placed at rest on a smooth horizontal surface. The man starts moving towards the end B with a velocity u_(rel) with respect to the trolley. The length of the trolley is L. As the man walks on the trolley, the centre of mass of the system (man+ trolley) :

A trolley filled with sand is moving with a velocity v on a smooth horizontal surface due to inertia. If the sand falls off at the rate of mu kg//sec , the velocity of the trolley as a function of time will be best represented by:

A container filled with liquid up to height h is placed on a smooth horizontal surface. The container is having a small hole at the bottom. As the liquid comes out from the hole, the container moves in a backward direction with acceleration a and finally, when all the liquid is drained out, it acquires a velocity v . Neglect mass of the container. In this case
