Got a lesson with vector addition and I need help with the last question.
17. Two forces with magnitudes 8 N and 11 N act on a large object. The angle between the forces is 30^o.
a) Draw a diagram to represent the combine effect of the forces.
b) Calculate the magnitude of the resultant force.
I have no idea on to do both. I drew a free body diagram and then used c^2 = a^2 + b^2. But that was correct. Then I used my law of cosines and that didn't work. Then I used my law of sines and that didn't work.
Could someone help me with a diagram. I think that will be best for me because I cannot interpret the question correctly.
