1. The problem statement, all variables and given/known data Object is oscillates such that displacement is x = (.222)sin(314t), where t is in seconds. In one period, the objects moves what distance? 2. Relevant equations What is the relationship between displacement, amplitude and distance? 3. The attempt at a solution The amplitude is the 0.222 m, so the displacement is four times that, as it moves from the centre to the edge, back to the centre, to the other edge and then back to the centre again, so the object moves 0.888 m. but WHY?????
