Question

What is the resultant force on a falling skydiver at an instant when the force of gravity on her is 720N and he force of friction is 480N?

Answer 1

Well, what happens when you take the vector sum of those two forces? What is the net force?

Answer 2

would it be 1200N

Answer 3

do you know what sort of equation i would need to find the answer?

Answer 4

Are the two forces acting the the SAME direction? I don't think so. So you can't just add them up together. One acts down and one acts up.

Answer 5

oh so its 720N-480N=240N

Answer 6

going down

Answer 7

Yes

Answer 8

ok thanks
