A skydiver reaches a constant velocity (known
as "terminal velocity") rather than continuing
to accelerate.
Suppose a particular skydiver (with all their
gear) has a mass of 63 kg . Given what you
know about Newton's Second Law of Motion
and the force of gravity near Earth, what force
must air resistance be exerting on the
skydiver when they have reached terminal
velocity?
(Give your answer in Newtons and as usual, just
give the number of Newtons without the unit
label.)
