A disc has mass 'M" and radius 'R'. How much tangential force should be applied to the rim of the disc so as to rotate with angular velocity `omega` in time 't'?

If a tangential force mg is applied to a disc of mass m and radius r, the angular acceleration produced in it is?

If a tangential force mg is applied to a disc of mass m and radius r, the angular acceleration produced in it is?

A uniform disc of mass M and radius R is rotating in a horizontal plane about an axis perpendicular to its plane with an angular velocity omega . Another disc of mass M/3 and radius R/2 is placed gently on the first disc coaxial. Then final angular velocity of the system is

Auniform disc of mass M and radius R is rotating in a horizontal plane about anaxis perpendicular to its plane with an angular velocity omega . Another disc of mass M/3 and radius R/2 is placed gently on the first disc coaxially. Then final angular velocity of the system is

A uniform disc of mass M and radius R is hinged at its centre C. A force F is applied on the disc as shown. At this instant, the angular acceleration of the disc is

A flywheel of mass 25 kg has a radius of 0.2 m. What force should be applied tangentially to the rim of the flywheel so that it acquires an angular acceleration of 2 "rad s"^(-2) ?

A flywheel of mass 30 kg has a radius of 0.2 m .What force should be applied tangentially to the rim of the flywheel so that it acquires an angular acceleration of 23 rad//s^2 ?

A uniform disc of mass m and radius R rotates about a fixed vertical axis passing through its centre with angular velocity omega . A particle of same angular velocity mass m and moving horizontally with velocity 2omegaR towards centre of the disc collides and sticks to its rim. The impulse on the particle due to the disc is
