A discus thrower accelerates a discus from rest to a speed of 24.3 m/s by whirling it through 1.30 rev. Assume the discus moves on the arc of a circle 1.01 m in radius.

(a) Calculate the final angular speed of the discus. _______________ rad/s (b) Determine the magnitude of the angular acceleration of the discus, assuming it to be constant. _______________ rad/s² (c) Calculate the time interval required for the discus to accelerate from rest to 24.3 m/s. ______________ s
