1. The problem statement, all variables and given/known data A tennis player takes 3 preparatory swings, each swing travels through an arc of 140 degrees each way. At the 4th swing, the ball is struck and the swing travels 240 degrees. Calculate the total angular distance and angular displacement of the club. 2. Relevant equations I have no clue, is it theta = d/r ? 3. The attempt at a solution I am so confused because all I am given is the arc and no radius. Is the angular distance in rads or meters? I can't seem to find the formula for this. I've taken physics and I know how to solve for angular velocity and angular acceleration but never did solve for angular distance. This is for my biomechanics class.
