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:

48.A block of mass 5kg is at rest on a smooth horizontal surface Water coming out of a pipe horizontally at the rate of 2kg/sec ,hits the block with a velocity of 6m/sec.The initial acceleration of the block is

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

A cart loaded with sand moving with velocity v. Sand is falling through the hole as shown in diagram then after falling on the ground sand is

A cart loaded with sand moving with velocity v. Sand is falling through the hole as shown in diagram then after falling on the ground sand is

A truck, carrying sand, moves with uniform velocity u on a smooth horizontal road. If Delta m mass of sand falls in time Delta t from the truck, then to maintain the speed u, the truck needs a force

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. The velocity of the man with respect to ground v_(1) will be:
