During a step, the force on the hip joint is approximately 2.5 times the weight of the person taking the step. For a single step, the joint slides approximately 30 mm inside the socket. The coefficient of kinetic friction for synovial fluid that lubricates the joint is 0.003. 3. If there is no synovial fluid, the coefficient of kinetic friction associated with the joint is 0.3. For this case, and for a 60 kg person, what is the absolute value of the work spent during a single step?
