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.

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 mass M is at rest over a smooth horizontal surface as shown in figure. Two boys each of mass 'm' are standing over the trolley. They jump from the trolley (towards right) with relative velocity v_r [relative to velocity of trolley just after jumping] (a) together (b) one after the other. Find velocity of trolley in both cases.

Find velocity of trolley in both cases.

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 spring block system is kept inside the smooth surface of a trolley as shown in figure. At t = 0 trolley is given an acceleration 'a' in the direction shown in figure. Write S - t equation of the block (a) with respect to trolley. (b) with respect to ground.

Find an expression for, the acceleration and speed of a trolley A under the action of a constant force F if it contains sand that pours out through the floor at the rate of mu per second. The speed of the trolley at t=0 was v=0 and the initital mass of sand and trolley was M_(0)
