A uniform ladder with mass m2 = 14kg and length L= 3.2m rests,against a smooth wall. A do-it-yourself enthusia of mass mi = 70kg stands on the ladder a distance d = 1.2m from the bottom (measured along the ladder.) There is no friction between the wall and the ladder, but there is a frictional force, with u, =0.25, between the floor and the ladder. Ni is the magnitude of the normal force exerted by the wall on the ladder, and N2 is the magnitude of the normal force exerted by the ground on the ladder. %3D
