Question

Sir Maverick is trying to capture a Pokémon from the Intramuros Castle by climbing a uniform ladder that is 5.0m long and weighs 200N. Maverick, who weighs 1000N, stops two-thirds of the way up the ladder to catch the Pokémon. The base of the ladder rests on a cobbled stone floor and leans in equilibrium against the frictionless vertical wall of the castle. The ladder conveniently forms a 3-4-5 triangle with the wall. Find:

a. The normal force on the ladder from the wall.

b. The normal force on the ladder from the floor.

c. The frictional force on the ladder and the floor.

d. The minimum coefficient of static friction that would prevent slipping at the base of the ladder.

e. The magnitude and direction of the net contact on the ladder at the base.
