A cylinder rotating at an angular speed ...

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 nd decelerating the moving one. If the common magnitude decelerating the moving one. If the common magnitude of the acceleration and deceleration be one revolution per second sqrare, how long will it take before the two cylinders have equal angular speed?
