Force A has a magnitude of 20 N and points in a direction of 150 degrees from the positive x axis. Force B has a magnitude of 6 N at an angle of 225 degrees. What is the resultant force A + B? 2. Suppose P(1, 2, 3) and Q(5, 0, 1). Find QP . 3D k is the unit vector in the positive z direction. PQ = q 1p 1 ( 29 i + q 2p 2 ( 29 j + q 3p 3 ( 29 k = q 1p 1 , q 2p 2 , q 3p 3 r v o r r v = v 1 2 + v 2 2 + v 3 2 ex. P(7, 1, 1) Q(0, 2, 3) Do: u = 2 ,1 , 4 , v = 1 , 3 , 4 , w =1 , 1 2 , 2 1. Find 2 uv . 2. Find a vector of length 3 in the same direction as v . 3. Are any vectors parallel? 4. Find point B if A(1, 3), AB = 10 , AB 3 , 4 ....
