Question

A skydiver is falling at constant velocity. If a force of 600 N is pulling down on the skydiver, how much force must be acting upward on the skydiver?
exactly 600 N
slightly more than 600 N
slightly less than 600 N
exactly 0 N

Answer 1

Well, if the skydiver is at constant velocity, than there’s no acceleration, as stated by Newton’s first law. Thus the total net force would equate to 0. In order to make this statement true, the answer would have to be exactly 600 N.

Answer 2

the answer is exactly 600 N. just did the test and got it right!
