A toddler weighs 10 kg and raises herself onto tiptoe (on both feet). Her feet are 8cm long with each ankle joint being located 4.5cm from the point at which her feet contact the floor. While standing on tip toe:
a.) What is the upward normal force exerted by the floor at the point at which one toddlers feet contacts the floor?
b.) What is the tension force in one of her achilles tendons?
c.) What is the downward force exerted on one of the toddlers ankle joints?
