A16.2 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 0.42 . the angle between the horizontal and the ladder is θ . the person wants to climb up the ladder a distance of 0.9 m along the ladder from the ladder’s foot. 16.2 kg 0.9 m 2 m θ b µ = 0.42 µ = 0 what is the minimum angle θmin (between the horizontal and the ladder) so that the person can reach a distance of 0.9 m without having the ladder slip? the acceleration of gravity is 9.8 m/s 2
