(17%) Problem 4: A uniform stationary ladder of length L = 5.6 m and mass M = 11 kg leans against a smooth vertical wall, while its bottom legs rest on a rough horizontal floor. The coefficient of static friction between floor and ladder is u = 0.41. The ladder makes an angle = 56° with respect to the floor. A painter of mass 8M stands on the ladder a distance d from its base. L Otheexpertta.com 33% Part (a) Find the magnitude of the normal force N, in newtons, exerted by the floor on the ladder.
