An 18.4 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 0.36 . The angle between the horizontal and the ladder is 55◦ . 18.4 kg d 4.9 m 55◦ b µ = 0.36 µ = 0 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/s 2 . Answer in units of m.
