Some bacteria are propelled by biological motors that spin hair-like flagella. a typical bacterial motor turning at a constant angular velocity has a radius of 1.57 x 10-8 m, and a tangential speed at the rim of 2.21 x 10-5 m/s.
(a) what is the angular speed (the magnitude of the angular velocity) of this bacterial motor?
(b) how long does it take the motor to make one revolution?
