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?

To throw a discus, the thrower holds it with a fully outstretched arm. Starting from rest, he begins to turn with a constant angular acceleration, releasing the discus after making one complete revolution. The diameter of the circle in which the discus moves is about 1.8 m. If the thrower takes 1.0 s to complete one revolution, starting from rest, what will be the speed of the discus at release?

1) Consider a system consisting of your instructor sitting on a stool while holding weights in his hands. The stool can spin; it rotates at a rate of 26 RPM. The instructor holds masses in each hand. When his arms are fully extended, the total rotational inertia of the system is 4.5 kg · m2. He then moves his arms close to his body, reducing the total rotational inertia to 1.5 kg · m2. If there are no external torques,...
