1. The problem statement, all variables and given/known data Four firefighters hold a square net, one at each corner. Each person exerts a force of 190 N whose line-of-action passes through a point just below the center of the net and makes an angle with the vertical of 50°. What is the net force the firefighters exert on the net? 2. Relevant equations F=ma 3. The attempt at a solution I've tried splitting the problem into four vectors and solving from there, but I cannot seem to get the correct answer. Also, don't the forces cancel out? I guess what I'm trying to say is that I'm lost. Any indication on how to start this one would really be appreciated.
