A student is holding a barbell as in the question above, but in this case we do not know whether
the barbell is moving and we do not know how it might be moving. The Earth is pulling down on
the barbell with a force equal to the weight of the barbell. Under these circumstances, which of
the following must be equal to the weight of the barbell? Choose all that apply. More than one
answer may be correct.
The upward force that the hand exerts on the barbell.
The upward force that the barbell exerts on the Earth.
O None of the other answers must be correct (every one of them could be wrong).
O The downward force that the barbell exerts on the hand.
