N 4 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 frictionless it exerts only a normal force N on the ladder The ladder has a length of L 4 1 m a weight of W 55 0 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 th ladder determine the following N N N a the forces exerted on the ladder when the person is halfway up the ladder Enter the magnitude only N N N N N b the forces exerted on the ladder when the person is three fourths of the way up the ladder Enter the magnitude only N N
