A small ball of mass m is attached to a very light string oflength L that is tied to a peg at point P. What is the magnitude ofthe horizontal velocity that must be applied to the ball so that itswings up and lands on the peg? Your answer can only contain thegiven information and any appropriate physical constants (such asg). If you have the acceleration of gravity g in your answer do notsubstitute numbers for it. You may introduce other variables tohelp you reach a solution but your final solution can only containthe given variables and g.
