Two children on the beach are pulling on an inner tube. One exerts a force of 45 N[N]. The other exerts a force of 60N[SW]. What is the net force acting on the tube
It is the vector sum of the two forcesw. Note that they are 135 degrees apart.
You can either add x- and y- components (separately) or use the law of cosines.
