WebQuestion: (10 points) Hill's equation describes the force-velocity property of skeletal muscle. For a muscle that is maximally stimulated, having a tension T' and a velocity of contraction v', the power (rate of doing work) is T'V'. At what force T' can this muscle develop maximum power? You will need to show this through a mathematical derivation. WebIntroduction.
