Question

A 76.0-kg person stands on a scale in an elevator. calculate the force reading ??1 on the scale when the elevator accelerates at 2.00 m/s2 downward.

Answer 1

Okay, to calculate the force reading on the scale, we use Newton's second law:

F = ma

Where F is the force, m is the mass of the person, and a is the acceleration.

* F = 76.0 kg * 2.00 m/s^2 = 152 N

So the force reading on the scale will be 152 N.
