1. The problem statement, all variables and given/known data A bag of sand weighing 100 N is hanging on the end of a long, light rope. The bag is pulled to one side by a horizontal force so that the rope makes an angle of 250 with the vertical. Find the magnitudes of the horizontal force and the tension in the rope. 3. The attempt at a solution I know that the horizontal force makes an angle of 1150 to the rope. I know that the magnitude of the horizontal force + the force on the rope equal 100N. I'm stuck on which way to go. Some sort of pendulum formula?
