Reference no: EM13678692

Assume a kid puts her bicycle on its back and starts the rear wheel spinning from rest to a final angular velocity of 250 rpm in 5 second.

(a) Evaluate what the angular acceleration?

(b) If she now slams on the brakes, causing an angular acceleration of - 87.3 rad/s2, determine how long does it take the wheel to stop?
