A rock stuck in the tread of a 63.0-cm-diameter bicycle wheel has a tangential speed of 2.80 m/s. When the brakes are applied, the rock's tangential deceleration is 1.00 m/s2.

(a) What are the magnitudes of the rock's angular velocity and angular acceleration at t = 1.40 s?

angular velocity = rad/s

angular acceleration= rad/s2

(b) At what time is the magnitude of the rock's acceleration equal to g?
