A uniform disc of mass M =2.50 kg and radius `R = 0.20` m is mounted on an axle supported on fixed frictionless bearings. A light cord wrapped around the rim is pulled with a force 5 N. On the same system of pulley and string, instead of pulling it down, a body of weight 5 N is suspended. If the first processis termed A and the second B, the tangential acceleration of point P will be:

A uniform disc of mass 2 kg and radius 1m is mounted on an axle supported on fixed frictionless bearings. A light chord is wrapped around the rim of the disc and mass of 1kg is tied to the free end. If it is released from rest-

Fig. shows a uniform disc of mass 1 kg and radius 0.2 m mounted on an axle supported in fixed frictionless bearings. A light string is wrapped around the rim of the wheel. A constant downwards pull of 2 kg wt. is exerted on the string. What is the angular acceleration of the wheel and the tangential acceleration of a point on the rim ?

A uniform disc of radius R and mass M is mounted on an axis supported in fixed friction less bearing. A light cord is wrapped around the rim of the wheel and suppose we hang a body of mass m from the cord. (a) Find the angular acceleration of the disc and tangential acceleration ofpoint on the rim. (b) At a moment t= 0, the system is set in motion, find the time dependence of the angular velocity of the system and the kinetic energy ofthe whole system.

A wheel of mass 1.4 kg and radius 0.4 m is mounted on a frictionless, horizontal axle as shown in Fig. 7.2.50. Alight string wrapped around the rim supports a mass of 2 kg. What is the angular acceleration of the wheel and the tangential acceleration of a point on the rim ? Also find the tension in the string.
