1. The problem statement, all variables and given/known data Determine the magnitude of the projection of force F = 700 N along the u axis 2. Relevant equations 3. The attempt at a solution A(-2, 4, 4) r(AO) = 2i -4j - 4k r(AO mag)= 6 u(AO) = 1/3i - 2/3j - 2/3k F(AO) = 233.3333i - 466.6667j - 466.6667k I'm not sure where to go from here. The only info I can figure about u is the 30 degree angle between it and the y axis.
