two gears are connected by a belt. the large gear has a radius of 20cm while the small gear has a radius of 10cm. if a point on the small gear travels at 16 rpm (revolutions per minute), find the angular velocity of the large gear. Tip: first find the velocity of the belt

Answer 1

same as ratio of circumferences

8 rpm = 8 * 2 pi radians/60 seconds
