Two wheel gears are connected by a chain. The larger gear has a radius of 5 centimeters and the smaller gear has a radius of 3 centimeters. The smaller gear completes 36 revolutions in 20 seconds.
What is the linear velocity of each of the gears in centimeters per minute?
The linear velocity of each of the gears is the same because they are connected by the chain (ANGULAR velocity for each is different though)
r = 3 36 revs/20 sec x 60 sec/min = 108 rev/min
3 cm * 108 rev/min x 2 pi /rev = 2035.75 cm/min
