A person stands on the ball of one foot. The normal force due to the ground pushing up on the ball of the foot has magnitude 750 N. Ignore the weight of the foot itself. The other significant forces acting on the foot are the tension in the Achilles tendon pulling up and the force of the tibia pushing down on the ankle joint. points Gastrocnemius- soleus muscles Tibia FAchilles FTibia eBook Achilles tendon Hint Print Calcaneus (heel bone) References If the tension in the Achilles tendon is 2246 N, what is the force exerted on the foot by the tibia? If the force is upward, enter a positive value. If the force is downward, enter a negative value. 2996 N
