A discus thrower moves the discus in 1.5 complete revolutions in 1.4 s (starting from rest). The radius of the circular path of the discus is 0.90 m, and the mass of the discus is 2.0 kg. Assume a constant torque is applied to the discus by the athlete.
(a) What is the angular speed of the discus just before release?
(b) What torque does the athlete apply to the discus?
(c) Approximately how far from the athlete does the discus land if it is released at a 45° angle to the horizontal?
