A 23.0 kg ladder is laid up against a smooth vertical surface. Friction between the floor and the ladder keeps it from slipping. The angle between the floor and the ladder is = 56.0°. B 7. A The length of the ladder is L = 3.50 m and its mass is distributed uniformly. There is no friction along the wall (surface parallel to segment OB) but there is friction along the floor (surface parallel to segment AO). (a) What is the net torque about point A?
