Problem
Consider a person of mass 60 kg standing on a set of weighing scales in an elevator.
(a) If the elevator is moving at a constant speed, determine the reading on the weighing scales.
(b) (i) If the elevator is accelerating downwards with an acceleration of 0.25g, determine the reading on the weighing scales. (g=9.81 ms−2)
(ii) How does this make the person feel?
(c) (i) If the elevator is accelerating upwards with an acceleration of 0.2g, determine the reading on the weighing scales. (g=9.81 ms−2)
(ii) How does this make the person feel?
