Have you tried the component method to add the vectors?
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.
Adding two vectors A and B graphically can be visualized like two successive walks, with the vector sum being the vector distance from the beginning to the end point. Representing the vectors by arrows drawn to scale, the beginning of vector B is placed at the end of vector A. The vector sum R can be drawn as the vector from the beginning to the end point
