A block is connected to an identical block through a weightless pulley by a weightless inextensible thread of length 2l (Fig). The left block rests on a table at a distance l from its edge, while the right block is kept at the same level so that the thread is unstretched and does not sag, and then released. What will happen first will the left block reach the edge of the table (and touch the pulley) or the right block hit and table?

As shown in figure, the left block rests on a table at distance l from the edge while the right block is kept at the same level so that thread is unstrectched and does not sah and then released. What will happen first?

Two blocks are connected by an inextensible string as shown. The pulley is fixed. If block A moves down with speed v, find the velocit of block B at instant.

A block of mass m is connected to another block of mass M by a spring (massless) of spring constant k. The block are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is unstretched. Then a constant force F starts acting on the block of mass M to pull it. Find the force of the block of mass M.

Two blocks are connected by a cord passing over a small frictionless pulley and resting on frictionless planes as shown in the figure The accleration of the blocks is-

Two blocks are connected by a cord passing over a small frictionless pulley and resting on frictionless planes as shown in the figure. The acceleration of the blocks is :

Figure shown a block P of mass m resting on a smooth floor at a distance l from a regid wall. Block is pushed towards right by a distance 3//2 and released. When block passes from its mean position another block of mass m_(1) so that the combined block just collides with the left wall.

A block of mass M is placed on the top of a bigger block of mass 10 M as shown in figure. All the surfaces are frictionless. The system is released from rest, then the distance moved by the bigger block at the instant the smaller block reaches the ground :

A block of mass 'm' is connected to another block of mass 'M' by a spring (massless) of spring constant 'k' The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is unstretched Then a constant force 'F' starts acting on the block of mass 'M' to pull it. Find the force on the block of mass 'm' :

Two loads of the same mass are tied to the ends of a weightless inextensible thread passed through a weightless pulley (Fig. ). Initially, the system is at rest,and the loads are at the same level. Then the right load abruptly acquires a horizontal velocity v in the plane of the figure. Which load will be lower in a time?
