ANSWER:
Step-by-step solution
Step 1 of 3
FN ; the reaction force exerted from the ground to the ball of the foot at point A.
When the person starts to elevate from the ground all the weight of the body stays on the ball of the foot. So
FN: the downward force exerted by the bone at point B
FT : the force exerted by the tendon upward to lift the body at point T.
