An athlete is sitting at a knee extension machine with a resistance 200 N, with the pad located 0.4 m below the knee. Assuming the quadriceps are the primary muscle group and are inserted 0.1 m below the knee, (1) what is the mechanical advantage of the lever system, (2) what is the minimum amount of force required (perpendicular to the lever) to rotate the machine upward? Show all work to receive credit. Mechanical Advantage: [BLANK-1] Force: [BLANK-2]
