Vectors A and B are shown in the figure. Vector C is given by C=B-A. The magnitude of vector A is 15.0 units, and the magnitude of Vector B is 5.00 units.
Part a) Find the vector C?
Part b) What is the magnitude of vector C?
The Attempt at a Solution
I drew these lines on the diagram and then solve for the sides using the angles with the SOHCAHTOA Method. Then after I found the sides I use the Pythagorean theorem to solve for side C. I am assuming vector C is the line connected with vector A and B.
Part b) the magnitude of vector C is 14.523.
Q: How to do part a? I don't understand what it means by finding vector C. Also is the above correct?
