[SOLVED] Rotational Motion question! 1. The problem statement, all variables and given/known data A wheel has a radius of 2.8 m. How far does a point on the circumference travel if the wheel is rotated through angles of 30 degrees, 30 radians, and 30 revolutions? 2. Relevant equations 3. The attempt at a solution I tried to use s=2pie(r) & theta=s/r but neither worked. This problem seems like it would be super easy, but I really have no idea how to do it! Help! Thanks!
