A girl and boy are moving a wagon full of books across the floor at a constant speed. We know the girls pulling the wagon at an angle of 36.9°. She is pulling with a force of 50 N and a boy is pushing with a force of 30N.  The mass of the Wagon and books together is 90 KG. Determine the force of gravity acting on the circled object, the normal force acting on the circled object, and the force of friction.
