Question

What force would a scale in an elevator on earth exert on a 53 kg person standing on it when the elevator speeds up at 3. 00 m/s^2 while moving upwards.

Answer 1

F = M g for person standing still

F = M (g + a) for person being accelerated upwards

F = 53 kg (9.80 + 3) m/s^2 = 678 Newtons
