Question

Compute all parts of given question:

Question: A 514-N physics student stands on a bathroom scale in an 814-kg (including the student) elevator that is supported by a cable. As the elevator begins to move, the scale reads 437N.

Part A: Find the magnitude of the acceleration of the elevator.

Part B: What is the acceleration if the scale reads 684N?

PArt C: If the scale reads zero, should the student worry? Explain.

Part D: What is the tension in the cable in part A?

Part E: What is the tension in the cable in part C?
