Question 1 Report
Given that p = (8N,030º) and q = (9N, 150º), find, in component from, the unit vector along(p - q).
p = 8cos30i + 8sin30jq = 9cos150i + 9sin150jp = 6.9282i + 4jq = -7.7942i + 4.5jpq = (-7.7942 - 6.9282)i + (4.5 - 4)jpq = -14.7224i + 0.5j|pq| = √((-14.7224)2 + (0.5)2)|pq| = √(216.7491 + 0.25)|pq| = √216.9991|pq| = 14.7309
the unit vector in the direction of p - q = −14.7224i+0.5j14.7309
-0.9994i + 0.0339j ≌ -i + 0.0339j
