A uniform disc of radius r and mass m is free to rotate on a frictionless pivot through point P on its rim as shown in Fig. The disc is at rest and is released from the position (1). (i) What is the speed of the centre of mass when the disc reaches the position (2). (ii) Also rind the speed of the lowest point on the disc in the dashed position.

A uniform rod of length L and mass m is free to rotate about a frictionless pivot at one end as shown in figure. The rod is held at rest in the horizontal position and a coin of mass m is placed at the free end. Now the rod is released The reaction on the coin immediately after the rod starts falling is

A uniform disc of mass M and radius R is supported vertically by a pivot at its periphery as shown. A particle of mass M is fixed to the rim and raised to the highest point above the center. The system is released from rest and it can rotate about pivot freely. The angular speed of the system when the attached object is directly beneath the pivot, is
