Some bacteria are propelled by biological motors that spinhair-like flagella. A typical bacterial motor turning at a constantangular velocity has a radius of 1.51 10-8 m, and a tangentialspeed at the rim of 2.14 10-5 m/s.
(a) What is the angular speed (the magnitude of the angularvelocity) of this bacterial motor?
? rad/s
(b) How long does it take the motor to make one revolution?
? s
