Ok, my question is, if you have 2 vectors added together a+b, could the magnitude of the resultant change if u subracted a-b? say a was any magnitude at 0 degrees. and b was any magnitude say 170 degrees. if u subtracted b it would go opposite direction southeast making the resultant much larger...
physics help!
:confused: Ok, I have understood every problem we have done so far except this one,
You are wearing shoes that have a coefficient of friction on rock of 0.70. On how steep a rock slope could you stand without slipping?
So far i have gotten:
Fs=Fparallel=
mu*W*costheta...
