Solved: Suppose you swing a ball of mass m in a vertical
Chapter 8, Problem 8.79(choose chapter or problem)
Suppose you swing a ball of mass m in a vertical circle on a string of length L. As you probably know from experience, there is a minimum angular velocity vmin you must maintain if you want the ball to complete the full circle without the string going slack at the top. a. Find an expression for vmin. b. Evaluate vmin in rpm for a 65 g ball tied to a 1.0-m-long string
