An accident victim with a broken leg is being placed on traction. The patient wears a special boot with a pulley attached to the sole. The foot and the boot together have a mass of 4.00 kg, and the doctor has decided to hang a mass of 6.00 kg from the rope. The boot is kept suspended by the ropes and does not touch the bed.

A) Determine the tension of the string using Newton's laws to analyze the hanging mass.

B) The net tensile force must pull the leg out. What is the right angle for the upper rope?

C) What is the net traction force that pulls the leg? Tip: If the pulleys do not have friction, which we will assume, the tension on the rope is constant from one end to the other.

D) Draw the movement diagram, identify the forces in the diagram, draw the free body diagram.
