he bicep curl is an exercise where you lift up a barbell with weights attached by bending your arms at the elbow. Assume your forearm length elbow to hand) is 0.516 m, and the barbell is lifted a vertical distance that is twice the forearm length. Also assume that the barbell is at rest at oth the start and the end of the motion. Calculate how much energy it takes to curl a barbell with a total weight of 72.8 lb? Image size: s ML Max
