A ring of mass m and a particle of the same mass are fixed on a disc of the same mass that the centre of mass of the system lies at the centre of the disc. The system rotates such that the centre of mass of the disc moves in a circle of the radius R with a constant angular velocity ω. From this, we conclude that

A cylinder rotating at an angular speed of 50 rev/s is brought in contact with an identical stationary cylinder. Because of the kinetic friction, torques act on the two cylinders, accelerating the stationary one and decelerating the moving one. If the common magnitude of the angular acceleration and deceleration be 1 rev/s2, then how much time (in seconds) it will take before the two cylinders have equal angular speed ?
