Question

If you were swingin a ball on a string around in a circle in a vertical plane, at what point in the path would the string be the most likelt to break? Explain why In what direction would the ball fly when the string broke?

Answer 1

the force on the ball at the bottom will be mg+mv^2/r. IF the string breaks, the ball then takes off horizontally from the bottom, then gravity will swing it down in a parabolic arc.
