A child of mass 43 kg stands on a scale inside an elevator. Select one or more: A. The scale would show his weight as 335.40 N when the elevator accelerates downward at 2 m/s2. B. The scale would show his weight as 507.4 N when the elevator accelerates upward at 2 m/s2. C. The scale would show his weight as 335.40 N when the elevator accelerates upward at 2 m/s2. D. The scale would show his weight as 335.40 N when the elevator decelerates upward at 2 m/s2. E. The scale would show his weight as 421.4 N when the elevator is stationary. F. The scale would show his weight as 335.4 N when the elevator decelerates upward at 2 m/s2. G. The scale would show his weight as 421.40 N when the elevator moves with a constant velocity 2.5 m/s.
