Aflywheel with a very low friction bearing takes 1.6 h to stopafter the motor power
is turned off. the flywheel was originally rotating at 41 rpm. whatwas the initial rotation rate in radians per second? answer in units of rad/s. how many revolutions does the flywheel make before it stops? answer in units of rev.

(I). The initial rotation rate is 4.29 rad/s.

(II). The revolutions is 3932.

Explanation:

Given that,

Time = 1.6 h

Angular velocity = 41 rpm

(I). We need to calculate the initial rotation rate in rad/s

(II). We need to calculate the revolutions

Using formula of revolutions

Hence, (I). The initial rotation rate is 4.293 rad/s.

(II). The revolutions is 3932.
