A disc of mass m and radius r is free to rotate about its centre as shown in the figure. A string is wrapped over its rim and a block of mass m is attached to the free end of the string. The system is released from rest. The speed of the block as it descends through a height h, is :-

A uniformaly thick wheel with moment of inertia I and radius R is free to rotate about its centre of mass (see fig). A massless string is wrapped over its rim and two blocks of masses m_(1)an d m_(2)(m_(1)gtm_(2)) are attached to the ends of the strung. The system is released from rest. The angular speed of the wheel when m_(1) descents by a distance h is :

A uniform disc of radius R and mass M is free to rotate only about its axis. A string is wrapped over its rim and a body of mass m is tied to the free end of the string as shown in the figure. The body is released from rest. Then the acceleration of the body is

A uniform disc of radius R and mass M is free to rotate about a fixed horizontal axis perpendicular to its plane and passing through its centre. A string is wrapped over its rim and a block of mass m is attached to the free end of the string. The block is released from rest. If string does not slip on the rim then find the acceleration of the block. Neglect the mass of the string.

The block shown in figure is released from rest. Find out the speed of the block when the spring is compressed by 1 m

A wheel whose radius is R and moment of inertia about its own axis is I, rotates freely about its own axis. A rope is wrapped on the wheel. A body of mass m is suspended from the free end of the rope. The body is released from rest. The velocity of the body after falling a distance h would be:

Two metal discs, one with radius r and mass m and the other with radius 2r and mass 2m , are welded together and mounted on a frictionless axis through their common center. (a) What is the total moment of inertia of the two discs? (b) A light string is wrapped around the edge of the smaller disc and a block of mass m_(0) is suspended from the free end of the string. If the block is released from rest at a distance h , what is its speed just before it strikes the floor?

Two masses M and m are connect by a light string gong over a pulley of radis r. The pulley is free to rotate about its axis which is kept horizontal. The moment of inertia of the pulley about the axis is I. The system is releaed from rest. Find the angular momentum fo teh system when teh mass Mhas descended through a height h. The string does not slip over the pulley.

A wheel of radius 20 cm and moment of inertia 1 kgm^2 can rotate about its centre.A string is wrapped over its rim and is pulled by a force 'F' tangential to the rim of wheel.If angular acceleration produced is 2 rad/ s^2 then the value of force 'F' is

A wheel of radius 10 cm can rotate freely about its centre as shown in figure. A stirng is wrapped over its rim and is ulle dby a force of 5.0 N. It is found that the torque roduces an angular acceleration 2.0 rad/s^2 in the wheel. Calculate the moment of inertia of the wheel.
