Question

A woman stands on a bathroom scale in an elevator that is not moving. The scale reads 588 N. The elevator then moves down at an acceleration of - 2.8 m/s2. What does the scale read while the elevator moves down

Answer 1

756 N.

Step-by-step explanation:

So, we are given the following data or parameters or information which is going to assist us in solving this particular Question or problem effectively;

=> The bathroom scale in an elevator is not moving.

=> " The scale reads 588 N. "

=> "The elevator then moves down at an acceleration of - 2.8 m/s2."

For the second point above: 588 N = mass × gravity.

Thus, the scale that will read while the elevator moves down is given below;

(Mass × gravity) - (mass × acceleration).

(The value of scale when it is not moving) × (1 + acceleration/gravity).

=> 588 × { 1 + 2.8/9.8} = 756 N
