What is the magnitude of a vector that makes an angle of 85º to the x -axis and whose x component is 12 m?
Answered by Evan
is it 137.7? The number I got seems to be a bit too big...
Answered by Damon
v cos 85 = 12
v = 12 / cos 85 = 12/ 0.087 = 13.9 we agree
if it is at almost 90 degrees to the x axis the of course the y component will be much greater than the x component.
