Physics

The dynamic duo of Je’Kai and Oluwalani have an acrobaticroutine where Je’Kai applies a 112 N external force to Oluwalani’shorizontally outstretched right leg at a point x = 0.35 m and y =0.03 m with his hip socket as the origin. Find the torque vectorabout the hip socket (origin) if the applied force during theroutine points in (a) the x-direction only and (b) if it points inthe z-direction only. Suppose that the 112 N external force isdirected vertically down through his leg’s center of mass, in they-direction, but does not include the 155 N weight of his own leg.If his rectus femoris in his quadricep is capable of applying aforce of 925 N along the muscle at an angle of 21˚ above thehorizontal at an attachment point of x = 0.45 m from the hipsocket, then (c) is the rectus femoris alone capable of sustaininghis leg in this position?
