(11%) Problem 5: A uniform stationary ladder of length L-2.6 m and mass M-18 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 -0.39. The ladder makes an angle 0-57° with respect to the floor. A painter of mass 8M stands on the ladder a distance d from its base. = 33% Part (a) Find the magnitude of the normal force N, in newtons, exerted by the floor on the ladder. X Attempts Remain N-264.6 33% Part (b) Find an expression for the magnitude of the normal force Ny exerted by the wall on the ladder. Nw-Mg cot? (16+d/2L) Nw 1/2Mg tan? (1+16d/L) Nw 1/2Mg cot?
