1. The problem statement, all variables and given/known data To throw the discus, the thrower holds the discus with a fully outstretched arm and makes one revolution as rapidly as possible to give maximum speed to the discus at release. The diameter of the circle in which the discus moves is about 1.7m. If the thrower takes 1.0s to complete one revolution, starting from rest, what will be the speed of the discus at release? 2. Relevant equations 3. The attempt at a solution I found the angular acceleration to be 2pi rad/s. I just dont know how to find the speed from there..
