A man of mass m stands on a frame of mass M. He pulls on a light rope, which passes over a pulley. The other end of the rope is attached to the frame. For the system to be in equilibrium, what force must the man exert on the rope?

The pulley arrangements shown in figure are identical, the mass of the rope being negligible. In case I the mass m is lifted by attaching a mass 2m to the other end of rope with a constant downward force F =2mg , where g is acceleration due to gravity The acceleration of mass m in case I is .

Two masses m_(1) = 5 kg and m_(2) = 10 kg, connected by an inextensible string over a frictionless pulley are moving as shown in the figure. The coefficient of friction of horiztonal surface is 0.15. The minimum height m that should be put on top of m_(2) to stop the motion is

Two moasses m_(1)=5kg and m_(2)=10kg, connected by an inextensible string over a frictionless pulley, are moving as shown in the figure. The coefficient of friction of horizontal surface is 0.15. The minimum weitght m that should be put on top of m_(2) to stop the motion is :-

Figure shows a pulley block system in which a block A is hanging one side of pulley and an other side a small bead B of mass m is welded on pe=ulley. The moment of intertia of pulley is I and the sytem is in equilibrium position when bead is at an angle alpha from the vertical. If the system is slightly disturbed from its equlibrium position, find the time period of its oscillations.

A system of two blocks A and B are connected by an inextensible massless string as shown in Fig. The pulley is massless and frictionless. Initially, the system is at rest. A bullet of mass 'm' moving with a velocity 'u' as shown hits block If and gets embedded into it. The impulse imparted by tension force to the block of mass 3m is
