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 string is wrapped around the rim of a wheel of moment of inertia 0.20 kg-m^2 and radius 20 cm. The wheel is free to rotate about it axis. Initially, the wheel is at rest. The string is now pulled by a force of 20 N. Find the angular velocity of the wheel after 5.0 seconds.

A metallic ring of radius r with a uniform metallic spoke of negligible mass and length r is rotated about its axis with angular velocity omega in a perpendicular uniform magnetic field B as shown in Fig. 3.163. The central end of the spoke is connected to the rim of the wheel through a resistor R as shown. The resistor does not rotate, its one end is always at the center of the ring and the other end is always in as shown is needed to maintain constant angular velocity of the wheel. F is equal to (the ring and the spoke has zero resistance)

A dics is rotating in a room. A boy standing near the rim of the disc of radius R finds the water droplet falling from the ceiling is always falling on his head. As one drop hits his head, other one starts from the ceiling. If height of the roof above his head is H , then angular velocity of the disc is

One end of a string is tied to a rigid support attached to roof and the other end is wound around a uniform wheel of radius r and mass m. The string is kept vertical and the wheel is released from rest. As the wheel descends show that (i) the tension in the string is one-third the weight of the wheel, (ii) the magnitude of the acceleration of the centre of mass is 2g/3 and (iii) the speed of the centre of mass is (4gh//3)^(1//2)

A bit of mud stuck to a bicycle's front wheel of radius r detaches and is flung horizontally forward when it is at the top of the wheel. The bicycle is moving forward at a speed v and it is rolling without slipping. The horizontal distance travelled by the mud after detaching from the wheel is:

A heavy disc with radius R is rolling down hanging on two non-stretched string wound around the disc very tightly. The free ends of the string are attached to a fixed horizontal support. The strings are always tensed during the motion. At some instant, the angular velocity of the disc is omega , and the angle between the strings is alpha . Find the velocity of centre of mass of the disc at this moment

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:

A cord of negligible mass is wound round the rim of a flywheel of mass 20 kg and radius 20 cm . A steady pull of 25 N is applied on the cord as shown in Fig. The flywheel is mounted on a horizontal axle with frictionless bearings. (a) Compute the angular acceleration of the wheel. (b) Find the work done by the pull, when 2 m of the cord is unwound. (c) Find also the kinetic energy of the wheel at this point. Assume that the wheel stars from rest. (d) Compare answers to parts (b)and (c).
