Select from A: a=0 m/s2, B: a=9.8 m/s2 down, C: a=9.8 m/s2 up, D: a > 9.8 m/s2 down, E: a < 9.8 m/s2 down, F: a > 9.8 m/s2 up, G: a < 9.8 m/s2 up, H: Not enough information E.g., if the first answer is A and the rest C, enter ACCCCC.
1) An elevator moving upward at constant speed
2) Just after a bullet is shot downward from a gun
3) An elevator starting on its descent

6) While a ball is in a person's hand during a downward throw
