1. The problem statement, all variables and given/known data A ball of mass 0.5 kg is attached to the end of a string of length 0.5 m. The ball rotates in a horizontal circular path about a vertical axis. The maximum tension on the string cannot exceed 324 N. What is the maximum possible angular velocity of the ball in rad/s ? 2. Relevant equations mω2/r = tension on the string. 3. The attempt at a solution I don't think the equation is correct. It should be v and not ω. However, what I wanted to do was to equate the centripetal force with the maximum force on the string. I got the answer as 18, which is not correct. I tried to use mg instead of m but that was wrong too. The correct equation is T = mg + mLω2, but why? Why can I not use the centripetal force equation here?
