A heavy flywheel rotating on its central axis is slowing down because of friction in its bearings. At the end of the first minute of slowing, its angular speed is 0.61 of its initial angular speed of 190 rev/min. Assuming a constant angular acceleration, find its angular speed (rev/min) at the end of the second minute.

At the end of 2nd minute, the angular velocity will be 0.61 th of 0.61 th of 190 rev/min Required angular velocity = 0.61 * 0.61 * 190 = 70.699 rev / min
