You could do it in just a couple of seconds if you really try. Find a place that's close to the equator, then do it on a day close to March 21 or September 21, at 12:00 noon, when the air is really clear. Keep your eyes wide open and don't squint. Good luck ! I know you can do it !

A 60 newton force is directed in a southwest direction. What are the magnitudes of the force components in the south and west di
JulijaS [17]
Hello
This question is to be tackled using vectors. When we look at the Southwest direction, we know it lies exactly between the South and West directions, producing an angle of 45 degrees. When we take sin(45) and multiply it by the original force, we obtain the component towards West; that is:
60 * sin (45) = 42.4 Newtons
And cos(45) gives us the force towards the South direction; that is:
60 * cos(45) = 42.4 Newtons
This can also be checked by using the formula of the magnitude of a vector and squaring 42.4, adding it to the square of 42.4 and then taking the square root of the answer.
sqrt(42.4^2 + 42.4^2) = sqrt(3600) = 60
