The centre of gravity for the ladder (mass = 10 kg) acts at point G as shown in the figure. Given the coefficient of statics friction between the floor and the ladder is HA = 0.3 and between the wall and the ladder is HB 0.2. Find the mass of the ball, m if the %3D ladder set-up is just about to slide.
