We are doing the force table lab in class and now we are calculating the f equilibran and the equilibrant angle. I had no time graphing a solution and came up with the right answers by measuring, but we are also suppose to do it purely mathematically and I do not know how to. I assume I will have to find vector componments, but I cannot get a right triangle in the first place. Please explain step by step.
Here are my problems:
100g 30* and 200g 220*
100g 30* and 200g 120* and 150g 330*
