3. [4 marks] and are unit vectors that make an angle of 58 with each other. a) Draw a vector diagram showing a and b, and another vector diagram showing the vector 3 - 46. b) Calculate the magnitude |3 - 46|. 4. [4 marks] Give the absolute bearing for each direction: a) W31S b) North Northwest c) N15E d) Southeast 5. [5 marks] A plane is travelling with an air velocity of 755 km/h [E16N]. There is a wind velocity of 47 km/h [W38N]. a) What is the plane's ground velocity? b) How long will it take the plane to fly 1818 km? 3.
