A constant force F is applied on a trolley of initial mass `m_0` kept over a smooth surface. Sand is poured gently over the trolley at a constant rate of `(mu)`kg//s`. Afer time t, find

(a) mass of the trolley (with sand)
(b) net force on the trolley
(c) velocity of trolley

A trolley of initial mass m_0 is kept over a smooth surface as shown in figure. A constant force F is applied on it. Sand kept inside the trolley drains out from its floor at a constant rate of (mu)kg//s . After time t find: (a) total mass of trolley and sand. (b) net force on the trolley. (c) velocity of trolley.

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. When the man starts moving, then the velocity of the trolley v_(2) with respect to ground will be:

A large trolley is kept at rest on a frictionless horizontal surface. There are same peple standing on the trolley. Initially no one is moving. C_(1) is centre of mass of trolley and C_(2) is centre of mass of trolley plus people. Now people start moving on the trolley.

A trolley containing water has total mass 1000 kg . Now water starts coming out of the trolley at the rate of 10 kg//s from below it. Find the velocity of the trolley after 50 sec,If the initial speed is 10 m//s on the horizontal frictionless road.

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:
