A 50.5 N object is in free fall. What is the magnitude of the net force
which acts on the object?

-49.49

Explanation:

If there’s no air resistance then the only thing acting on the object is the force of gravity which is mass times gravity. And to get mass all we have to do is divide 50.5/10 then times that by -9.8 since that’s the force of gravity.

The answer would be 50.5 N.

Explanation: It’s because there’s no air resistance.
