A 20.8 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 0.12. The angle between the horizontal and the ladder is 6. The person wants to climb up the ladder a distance of 0.72 m along the ladder from the ladder's foot.
What is the minimum angle Omin (between
the horizontal and the ladder) so that the
person can reach a distance of 0.72 m without
having the ladder slip? The acceleration of
gravity is 9.8 m/s2
