Calculate the reactive force and reactive muscle moment atJustin Verlander’s knee for a seated leg extension, with a weightof 55, 75, and 95 lbs. Assume that the leg is held at an angle ??,and if it were fully extended, then ??=0. Assume that the load isapplied in a way such that it remains perpendicular to the lowerleg. Justin Verlander is 1.96 meters tall and has a mass of 102 kg.(Note the units!) a. State ALL of your assumptions. b. Calculatethe force and reactive muscle moments in terms of ??. c. Solve forthe force and reactive moments for each load at ?? = 90̊, 60̊, 30̊,0̊.
