Draw starting from the origin of the axes provided. Each unit on the graph is 100 .
Three people pull horizontally on ropes attached to a post, as shown in the figure. The total force that they exert on the post is zero. One of them pulls directly north with f1 = 500 N . Another pulls with f2 = 400 N in a direction 60 west of north. Find the magnitude and direction of the force f3 exerted by the third person so that the sum of the three forces is zero.
