Three friends tie three ropes in a knot and pull on the ropes in different directions. Adrienne (rope 1) exerts a 100-N force F(AonK) that points 30 degrees below the positive x-axis and Jim (rope 2) exerts a 160-N force in the negative y-direction. How hard does Luis now have to pull the knot so that it remains in equilibrium? In what direction does Luis now have to pull the knot so that it remains in equilibrium (clockwise from the negative x-axis)?
