An 66 kg man is climbing up a 7.0 m ladder that is resting against a smooth, frictionless wall. The ladder has a mass of 10 kg and it makes an angle of o=58° with the ground. The maximum horizontal force the ground can exerts to support the ladder is 342.0N. At what position, measured from the bottom along the ladder, as the man climbs the ladder will start to collapse? Answer: 5.55 m.

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. N2 mg Since the floor is rough, it exerts both a normal force N, and a frictional force f, on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L = 4.7 m, a weight of W, = 64.5 N, and rests against the wall a distance d = 3.75 m above the floor. If a person with a mass of m = 90 kg is standing on the ladder, determine the following. (a) the forces exerted on the ladder when the person is halfway up the ladder (Enter the magnitude only.)
