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))`

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 :-

Two blocks of masses of 40 kg and 30 kg are connected by a weightless string passing over a frictionless pulley as shown in the figure.
