(adsbygoogle = window.adsbygoogle || []).push({}); Ok, last problem of the day lol.. I have found one answer to the problem already, I just need the other half. I'm confused about it though. Please help, thanks. Here Goes:

Two people pull on a stubborn mule, as seen from a helicopter. The picture is like this:

_V_

0

Ok, in the middle of V it is the y-axis. In quadrant I and II there are a vector in each. The 0 is the mule that they are pulling on.

In quadrant II, they angle is 75 degrees, the Force is 80 N.

In quadrant I, the angle is 60 degrees, the Force is 120 N.

Find a) the single force that is equivalent to the two forces shown, andb) the force that a third person would have to exert on the mule to make the net force equal to zero.

My answer for a):

I got 184 N force at +78 degree north of west.

I used graphical methods(daisy chain, by connected the tail of vector(80 N) to vector (120 N).

How do I find the force that a third person would have to exert on the mule to make the net force equal zero?? I don't even get what a net force is =P
