A 519-N physics student stands on a bathroom scale in an 891-kg (including the student) elevator that is supported by a cable.

As the elevator starts moving, the scale reads 446 N. Find the magnitude and direction of the acceleration of the elevator.

What is the acceleration (magnitude and direction) if the scale reads 656 N ?

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

What is the tension in the cable in part a?

What is the tension in the cable in part c?
