Surfing For Physics Formulas For Distance?
Lisa asks…Need help with physics question: A car travels 35 km west, 90 km north. What distance did it travel?I know these questions are very simple and this is just review for me, but Im forgetting the concept, of what I should be doing with the numbers, and what "direction" the final answer can be, and how to determine this. Should I be doing it like this: d=d1 - d2, d=35-90, d= -55 (west or east??) or is this even right? Other questions that I have trouble with are: An airplane flies 250
