a. What force in newtons should the woman in the figure exert on the floor with each hand to do a push-up? Assume that she moves up at a constant speed. _______ N   b. The triceps muscle at the back of her upper arm has an effective lever arm of 1.76 cm, and she exerts force on the floor at a horizontal distance of 18.0 cm from the elbow joint. Calculate the magnitude of the force in newtons in each triceps muscle. _________ N    Compare the magnitude of the total force exerted by both triceps muscles to her weight.   total force exerted by both triceps muscles/her weight =   c. How much work does she do in joules if her center of mass rises 0.255 m? _______ J
