A 75 kg person escapes from a burning building by jumping from a window 25 m above a catching net. Assuming that air resistance exerts a 95 N force on the person during the fall, determine the person's velocity just before hitting the net.
My main problem is finding the force of the person... do you take 9.81*75 and minus 95 to get the downward force of the person?
ok, thanks. I think I'm on the right track.
Yes. The force down is mg minus air resistance.
