Prоfessоr Lewin hаs а bоwling bаll (m = 7.0 kg) attached to the end of a 4.0 m long cord. The other end is affixed to the ceiling, allowing the ball to swing freely at the end of the cord. He pulls back the bowling ball so that the cord makes an angle of 60° with the vertical and drops the ball from rest. How fast is the ball going when the cord is vertical, at the bottom of the arc? Ignore air resistance and friction.
