Physics

A person with mass m=80 kg is training for pushups. Assume thatthe distance between the shoulders and the feet is 1.5 m, and thecenter of mass is at 1 m from the feet. First, he is trying to do anormal pushup. Assuming only vertical forces, what is the force onthe arms?After that proved to be too difficult, he tries a modifiedversion, where his arms are on the kitchen counter instead (~92 cmfrom the ground), which causes his body to form a 450 angle withthe ground. What is the force on the arms, and what happens as theperson expands their arms?
