HUYYYP LEASE A 21.9 kg person climbs up a uniform ladder with negligible mass. The upper end of the ladder rests on a frictionless wall. The bottom of the ladder rests on a floor with a rough surface where the coefficient of static friction is 0.52 . The angle between the horizontal and the ladder is 57. When the person attempts to climb the ladder, how far up the ladder will the person reach before the ladder slips (kaboom)? The acceleration of gravity is 9.8 m/s2 *
