A box with a 75kg passenger inside is launched straight up into the air by a giant rubber band. After the box has left the rubber band but is still moving upward: Answer those two questions!

Actual weight is the downward force exterted by the body.
Aparent weight is the upward force exerted by the body.
Usually the apparent weight is equal to the actual weight but in your description you said that body is in flight which is an exceptional case.
You can use Newtons second law for solving this problem.
An example of apparent weight calculation for vertically moving body (and a nice reference) can be found on this page

after the box is just released from the rubber band, there is no acceleration anymore, and besides you can neglect buoyance force in air due Archimedes law, hence apparent weight equals true weight eguals 75 kg.
