for the question i need to do the following 1- Draw a free body diagram2. set up a coordinate system. You must correctly follow our rule to align the net acceleration for thesystem to be along a single axis (it cannot have an x- and a y-component).3. Correctly set up Newton’s Second Law (sum of the forces) in both the x- and y- direction. Correctly useeither sinθ or cosθ as appropriate. question ----- Your physics professor told you that you feel heavier or lighter in an elevator at the beginning or end ofyour vertical voyage. You want to test if your weight ACTUALLY changes, so you take a bathroom scalewith you to the rickety elevator in Elings hall. You hop on at the second floor and step onto the scalebefore pressing the button to travel down to the first floor. Before the doors close, while the elevatorisn’t moving, you have a weight of 934 ?. As soon as the elevator starts downward, the scale reads813 ?. What is the magnitude of the acceleration of the elevator?
