Reference no: EM13301603

A cyclist hits the brakes and decelerates. His wheels were spinning at 175 rev/min initially and 40 rev/min after 5 s of deceleration.

(a) Compute the average angular acceleration (in rad/s2) of his wheel during this 5 s period.

(b) How long does it take him (altogether) to come to a complete stop if he maintains the same acceleration?
