Question
An 88kg person stands on a uniform ladder 4 0m long, that weighs 70N. as shown in the figure The floor is rough hence, it exerts both a normal force, f1, and a frictional force, f2. on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, f3 Using the dimensions given in the figure, find the forces exerted on the ladder when the person is halfway up the ladder Express your answers using two significant figures Find the forces exerted on the ladder when the person is three-fourths of the way up the ladder Express your answers using two significant figures separated by commas.
