A cord is wound round the circumference of wheel of radius r. The axis of the wheel is horizontal and the moment of inertia about it is I. A weight mg is attached to the cord at the end. The weight falls from rest. After falling through a distance 'h', the square of angular velocity of wheel will be :-

A cord is wound round the circumference of wheel of radius r . The axis of the wheel is horizontal and fixed and moment of inertia about it is I . A weight mg is attached to the end of the cord and falls from rest. After falling through a distance h , the angular velocity of the wheel will be.

A cord is wound round the circumference of a solid cylinder radius R and mass M . The axis of the cylinder is horizontal. A weight mg is attached to the end of the cord and falls from rest. After falling through a distance h .

A cord is wound round the circumference of a solid cylinder radius R and mass M . The axis of the cylinder is horizontal. A weight mg is attached to the end of the cord and falls from rest. After falling through a distance h . If the mass starts from rest and falls a distance h , then its speed at that instant is:

A cord is wound around the circumference of a wheel of diameter 0.3 m. The axis of the wheel is horizontal. A mass of 0.5 kg is attached at the end of the cord and it is allowed to fall from rest. If the weight falls 1.5 m in 4s, what is the angular acceleration of the wheel ? Also find out the moment of inertia of the wheel.

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 ?
