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.
