This video picks up from Part 3 where we discussed adding and subtracting vectors when facing in the same and opposite directions.
But the MCAT is designed to be tricky, and so you will likely find yourself faced with a problem combining vectors at some odd angle off the x-axis or y-axis.
This video shows you a simple method for adding and subtracting these tricky vectors using their vector components along with the Pythagorean Theorem.

Thanks Leah for this tutorial video. In this question I used the angle of 30 degrees, not 60 degrees, and the final answer was R= 73.85 m. Do you think my method is correct?
In the task featuring a running dog shouldn’t y2 be negative since R2 is in the negative directon?
