E: .'E-i m o let: P E- n d u lu m A pendulum is formed from a small ball and a string of length L A peg is at a height Rahove the pendulum's lowest point [note: i. :2: R]. What is the minimum height above the pendulum's lowest point that the ball must be released for the ball to make it completely around the peg without the string going slack? A light spring of elastic constant it is attached via a string and a light pulleyr to a bloclc of mass lT'ls resting on a horizontal surface. The other end of ms is attached to a second block of mass ms that is hanging ouera light pulley of ne gible friction. ms is initially held at rest such that the spring Is at its equilibrium position. If the coefficient of kinetic friction between the block and the surface is us, what is the maximum distance that \"1-1. will slide
