Solve the all parts of given question:
Question: A 540 N physics student stands on a bathroom scale in an 850-kg (including the student) elevator that is supported by a cable. As the elevator starts moving, the scale reads 440 N.
Part A: Find the acceleration of the elevator (magnitude and direction -- take up to be the positive direction)?
Part B: What is the acceleration if the scale reads 660 N?
Part C: What is the tension in the cable in parts (a) and (b)?
