Represent the 400N Force in Cartesian vector format. Use x=20m, y=15m.
D (0,0,24)m
A (20,15,0)m
position vector (from D to A) rDA = [20i+15j-24k]m
magnitude of rDA = length of DA = distance btwn DA = = 34.7
uDA = position vector rDA / magnitude rDA = 0.576i + 0.432j - 0.962k
F400 = 400 uDA = [231i + 173j - 277k]N
F400 = <230.8,173.1,-277>N
