An inextensible thread is attached with a pulley. A block of mass `m_2 = 100 gm` is hanged from,the thread. The thread is pulling a block of mass `m_1 = 200 gm`, which is kept' on a smooth table. Find- out the tension of the thread and acceleration of the blocks.

A block of mass 5 kg lies on a horizontal frictionless plane. A string attached to it passes over a smooth pulley fixed to the edge of the plane and carries a load of mass 1 kg. Find the acceleration of the system.

Two masses m_(1) and m_(2) are connected to the ends of string passing over a pulley. Find the tension and the acceleration associated.

A bullet of mass 50 g , moving with a velocity of 50 m*s^(-1) hits and enters a wooden block of mass 2kg and comes to rest within it. The wooden block was initially at rest on a smooth table. Find the final velocity of the wooden block. What are the initial and final kinetic energies of the block-bullet system?

A block of mass M is kept on a smooth horizontal surface. Another block of mass m, moving with velocity v, collides with it and coalesces. What is the resultant velocity of the system?

A bullet of mass 50 g is fired into a wooden block of mass 2 kg resting on a smooth table surface. The bullet entres at 50 m*s^(-1) and gets embedded in the block. Find the final velocity of the block. Find the initial and the final kinetic energy of the block -bullet system.
