While the elevator is still parked at the second floor, what is the reading of the scale? Convert your answer to pounds and use lbs as units. A 89.8-kg student is entering an elevator on the 2nd floor of the library and steps on a bathroom scale that happens to be there. The student pushes the button to the 5th floor; the doors close and the elevator begins to speed up at a constant rate of 0.814 m/s^2. While the elevator speeds up, what is the reading of the scale? Convert your answer to pounds and use lbs as units. (Practice how to properly work this out. Start with a sketch of the situation. Then draw a proper force diagram, aka free-body diagram. Explain your diagram. Apply Newton's Law and find the answer. Practice how to explain all your steps along the way; what you are doing and why; explain why you are drawing the diagram the way you do. Finally, evaluate your answer.)
