The acceleration a of trolley so that block of mass m remains stationary with respect to rough trolley as shown in the figure, is m Trolley 0 - ...

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)

Two trolley 1 and 2 are moving with acceleration a_(1) and a_(2) respectively, in the same direction. A block of mass m on trolley 1 is in equilibrium from the frame of observer stationary with respect to trolley 2. the magnitude of friction force on block due to trolley is (assume taht no horizontal force other than friction force is acting on block).

A particle is projected from a stationary trolley. After projection, the trolley moves with a velocity 2(sqrt15) m//s . For an observer on the trolley, the direction of the particle is as shown in the figure while for the observer on the ground, the ball rises vertically. The maximum height reached by the ball from the trolley is h meter. The value of h will be .......... .

A trolley of mass M is attached to a block of mass m by a string passing over a frictionless pulley as shown in the figure. If the coefficient of friction between the horizontal surface and wheels of trolley is mu , then acceleration of the block m and that of trolley M on releasing the system is :-

A trolley of mass 20 kg is attached to a block of mass 4kg by massless string passing over a frictionless pulley as shown in the figure. If the coefficient of kinetic friction between trolley and the surface is 0.02, then the accderal ion of the trolley and block system is ("Take" g=10ms^(-2))

What is the acceleration of the block and trolley system shown in if the coefficient of kinetic friction between the trolley and the surface is 0 .04 ? What is the tension in the string ? Take g = 10 ms^(-2) Neglect the mass of the string .

A trolley was moving horizontally on a smooth ground with velocity v with respect to the earth. Suddenly a man starts running from rear end of the trolley with a velocity (3//2)v with respect to the trolley. After reaching the other end, the man turns back and continues running with a velocity (3//2)v with respect to trolley in opposite direction. If the length of the trolley is L, find the displacement of the man with respect to earth when he reaches the starting point on the trolley. Mass of the trolley is equal to the mass of the man.

A trolley is moving horizontally with a constant velocty of v m//s w.e.t. earth. A man starts running from one end of the trolley with velocity 1.5v m//s w.r.t. to trolley. After reaching the opposite end, the man return back and continues running with a velocity of 1.5 v m//s w.r.t. the trolley in the baclward direction. If the length of the trolley is L then the displacement of the man with respect to earth during the process will be :-
