A hamster runs at a speed of 8 centimeters per second in a wheel of radius 15 centimeters.

Question

a) What is the angular velocity of the wheel? (in radians/sec) 

b) How fast will the wheel spin in revolutions per minute?  

Answer 1

a) What is the angular velocity of the wheel? (In radians/sec) 



angular velocity(omega)=linear velocity/radius=8/15 radian/sec

b) How fast will the wheel spin in revolutions per minute?  

(8/15) *60=32

32/(2pi) =5.09 RPM
