· Recall that vectors can be added or subtracted using the paralleloram law. This is a variation or the triangle law. In both cases we are putting vectors head to tail. These methods favor drafting solutions to porblems that are not really necessary with calculators, but they are still very useful for understanding.
· vectors can be added to get resultant forces in vector (rectangular component) form.
· We can also represent the same forces as scalar magnitudes, and direction,
· we could have also solved this problem using trigonometry.
