Question

a student that weighs 436 n is standing on a scale in an elevator and notices that the scale reads 498 n. from this information, the elevator is:

Answer 1

The elevator has constant acceleration upward

Given that a student that weighs 436 N is standing on a scale in an elevator and notices that the scale reads 498 N.

The formula of force can be derived from the Newton's second law of motion, which states that the force exerted by any object equals mass times the acceleration of that object i.e., F = ma

Net force = mg + ma

498 = 436 + ma

62 = 436 a/ 9.8

a = (62 x 9.8) / 436

a = 1.39 m/s²

Hence, it is clear that the elevator has constant acceleration upward.
