To throw the 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 1.6 m.If the thrower takes 0.90 s to complete one revolution, starting from rest, what will be the speed of the discus at release?
