Gear A, with a mass of 1.75 kg and a radius of 55.0 cm, is in contact with gear B, with a mass of 0.875 kg and a radius of 30.0 cm.The gears do not slip with respect to each other as they rotate. Gear A rotates at 128 rpm and slows to 64.0 rpm in 4.95 s.
How many rotations does gear B undergo during this time interval?
