A discus thrower moves the discus in 1.70 complete revolutions about his body in 1.32 s (starting from rest). The radius of the circular path of the discus is 0.900 m, and the mass of the discus is 2.00 kg. Assume that a constant torque is applied to the discus by the athlete. What torque does the athlete apply to move the discus about his body?
