(c) A ladder with length L and mass m rests against a wall. Its upper end is a distance h above the ground (Figure 13.3). The center of gravity of the ladder is one-third of the way up the ladder. A fire fighter with mass M climbs halfway up the ladder. Assume that the wall, but not the ground, is frictionless. Write the sum of the forces in (i) x-direction and (ii) y-direction and (iii) the expression for the sum of the torque about the point where the ladder makes contact with the ground(O).
