Question
A ladder with a length of 5.0 m and a weight of 650N is placed so its base is on the ground 4.0 m from a vertical frictionless wall, and its tip rests 3.0 m up the wall. The ladder remains in this position
only because of the static friction force between the ladder and the ground. You, with a weight of 500 N, are standing on the ladder at a horizontal distance of 1.10 m from the wall. Assume the mass
of the ladder is uniformly distributed.
(a) Find the magnitude of the upward normal force applied by the ground on the ladder.
(b) Find the magnitude of the horizontal normal force applied by the wall on the ladder.
N
(c) Determine the minimum possible coefficient of static friction for the ladder-ground interaction, for the ladder to remain at rest.
