A discus thrower accelerates a discus from rest to a speed of 25.4 m/s by whirling it through 1.21 rev. Assume the discus moves on the arc of a circle 0.95 m in radius. A discus thrower moving in a circle as he prepares to throw the discus. (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 25.4 m/s. s
