[QUOTE="Student4Life, post: 6070302, member: 652118"] [h2]Homework Statement[/h2] :[/B] One swings a rock at the end of a string. We wish for the string to remain taut and for the rock to travel in a circulat path, in a vertical plane. What mathematical condition must the centripetal acceleration of the rock satisfy for the string to remain taut when the rock is at its highest point?[h2]Homework Equations[/h2] :[/B] [F[/c] = m[v][/2] / r ? [h2]The Attempt at a Solution[/h2] So far I come up with this equation to define what is going on but I am not sure [B][F[/c] = m[v][/2] / r ?[/B] [/QUOTE]
