3. Consider two vectors u = 2i -j +2k and v=3i+2j-k. (a) Find a vector orthogonal to a and b. _ [3 marks] (b) Show that the vector from (a) is orthogonal to a and b. [1 mark]
Determine the angle between u and v The angle between u and v is (Type an integer or a decimal rounded to the nearest hundredth as needed.) The wind is blowing at a speed of 31 mph in a direction of S 48 W. Express the velocity of the wind as a vector in terms of i and j The vector for the wind velocity in terms of i and j is v-(Di(i (Round to two decimal places as needed.)
