Whimsical interior decorating Dr. Aarnio is afraid of heights so she's leaned her ladder against the wall and hung a plant From it for decoration (might as well use it for something). The ladder (weighing 382 N) is at an angle of 52D relative to the floor and it's 4.5 m long. The plant, 2.32 kg, is hung 1.125 m up from the base of the ladder: Assume the wall is Frictionless but the floor is not; static friction is keeping the ladder from sliding. a) Calculate the normal force of the floor on the foot of the ladder. b) What is the normal force of the wall on the top of the ladder? :x N c) What is the static friction coefCIent between the ladder and the oor
