A hamster running in a wheel of radius 10 cm spins the wheel one revolution in 11 seconds.

Question

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

b) At what linear velocity is the hamster running? (in cm/sec)  

Answer 1

a) One revolution is 2pi radians.

Omega(angular velocity) = (2pi)/11 = about .571 radians/sec

b) v = rxOmega = 10(.571) or abou 5.71 cm/sec
