Question

A 96.0 kg person stands on a scale in an elevator. What is theapparent weight in each of the following situations? a) When the elevator is accelerating upward with anacceleration of 1.80 m/s^2? b) When the elevator is moving upward at a constantspeed? c) When the elevator is accelerating downward with anacceleration of 1.60 m/s^2?

Explanation / Answer

F = m a wapp - w = m a wapp = w + m a = m g + m a = m(g + a) m = 96 kg g = 9.8 m/s2 For part (a), a = 1.8 m/s2 For part (b), a = 0 For part (c), a = -1.6 m/s2
