A 2.0-m-long, 11-kg ladder is resting against a house wall, making a 35 ∘ angle with the vertical wall. The coefficient of static friction between the top of the ladder and the wall the coefficient is 0.00:
A. Determine the minimum coefficient of static friction between the ladder feet and the ground needed for the ladder to stay in rest.
B. Determine the magnitude of the normal force of the wall on the ladder.
C. Determine the magnitude of the normal force of the floor surface on the ladder.
D. Determine the magnitude of the force of friction between the floor and the ladder.
