A 25.3 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 0.25. The angle between the horizontal and the ladder is 0. The person wants to climb up the ladder a distance of 0.85 m along the ladder from the ladder's foot. 2.2 m 0.85 m 25.3 kg 11 0.25 0 0 = 11 What is the minimum angle Omin (between the horizontal and the ladder) so that the person can reach a distance of 0.85 m without having the ladder slip? The acceleration of gravity is 9.8 m/s Answer in units of . Answer in units of
