An object with a mass m = 150 kg is suspended from the ceiling at point A with a weight-less rope, while an athlete is pulling with a second rope, attached at point B, applying a force F. The whole system is in equilibrium. Given the geometry shown in the figure, draw the appropriate free body diagram and then calculate the magnitude of the force F applied by the athlete, as well as the tension $T_{AB}$ in the rope AB.
