As shown in the figure, a bob of mass m is tied by a massless string whose other end is wound on a fly wheel Ring of radius r and mass m. When released from rest the bob starts falling vertically. When it has covered a distance of h, the speed of the bob will be :

As shown in the figure, two bobs of masses m & 2m are tied by a massless string which is wound on a fly wheel (disc) of radius r and mass m. When released from rest the bob of mass 2m starts falling vertically. When it has covered distance of h, the angular speed of the wheel will be:

In the 1st figure shown here rod is massless and at its end a bob of mass m is attached. The other figure is a uniform rod also of mass m. As they are released, at the bottom

A chord is tied to a wheel of moment of inertia I and radius r . The other end is attached to a mass m as shown. If the mass m falls by a height h then the square of angular speed of the wheel is ?
