A bodybuilder configures a leg-press apparatus to a resistance of 230 lb (about 1000N). She pushes the weight to her full extensionand comes to rest. A). What is her normal force on each of her feet. B). Assume she is able to move the push-plate of theleg-press machine at an acceleration of .50 m/s2 for thefirst half of the displacement. What is the normal force on each foot during this period of acceleration? Assume the resistive forceis due to a weight of 230 lb hanging from the end of the cable.
