Answers without supporting work will not receive credit. lem. • "Boz" your final answers to problems. 1. (1 point) Write the vector v in the form ai + bj. if v = 2. (4 points) A plane flies N30°W at 450mph and encounters a wind blowing due west at 30mph. (a) Express the velocity of the plane Vp relative to the air as a vector. (b) Express the velocity of the wind vw as a vector. (c) Find the true velocity vr and the the true speed of the plane. 3. (1 point) Find the angle between v = (8,3) and w = (4.-3) 4. (3 points) Given v = (-8,-4) and v = (-6,4). Find two vectors V, and V2 such that V, is parallel to W, V2 is orthogonal to w, and vi + V2 = v.

Answer 1

o mang ditude of vector 3= 151 = 2 arrection angle O= 45 Therefore rector lies in quardant II X Component of vector 3: El cosso = VA cos (45) - I costata) - Vit x Cos (5) = VE x-I = - VE y component of vector E= 15 Bino = VII sin (4) - Ja sin (a+5) - JIExsinch-x-42-5 vector Form = - VI? - VSI § is in form of að + bj where az = Vit b = -V51
