Problem 5: Consider the forces involved in doing push-ups. The woman's weight acts as a |force exerted downward on her center of gravity (marked CG in the figure). You may assume that the angle between her body and the floor is small enough so that the small angle approximation is valid throughout this motion. m = 50 kg CG w Freaction 0.90 m 1.50 m Part (a) Calculate the force, in newtons, the woman in the figure exerts to do a pushup at constant speed. F; =
