Consider the woman doing push-ups in the figure. She has a mass of 51.3 kg, CG and the distance from her feet to her center of mass is 0.85 m, while the distance from her feet to her hands is 1.7 m. a Freaction The triceps muscle at the back of her upper arm has an effective lever arm of 1.25 cm, and she exerts force on the floor at a horizontal distance of 16 cm from the elbow joint. Calculate the magnitude of the force in newtons for each triceps muscle. What is her useful power output, in watts, if she does 25 pushups in one minute? For the sake of simplicity, ignore any power used by her muscles lowering her body during each pushup.
