1. The problem statement, all variables and given/known data If a ball is being twirled in a circle with a radius of 0.5m, and then is let go such that the balls velocity makes an angle 30 degrees from the horizontal and then covers a distance of 1,000m before it hits the ground. What was the centripetal accelertaion provided by the string?? Picture provided 2. Relevant equations Ac = v^2 / r 3. The attempt at a solution I don't really understand how to get the velocity in order to just plug in everything else into the equation.
