A bus leaves the school at (5, 3) and travels west at a speed of 102 km/h for 5 hours. Then, it turns to travels north at a speed of108 km/h for 3 hours. East = positive x and North = positive y. a) Sketch the two displacement vectors to scale. Then draw their overall displacement vector. Where is the bus in the end? b) Calculate the overall displacement vector of the school bus, expressed in both the vector form, such as "(1, -2)", and the magnitude [angle] form, such as "11.22 km [E 3344" N]", 2 decimal places. c) Sketch the two velocity vectors to scale. As the car turns in the middle of the journey, draw the change in its velocity vector. d) Calculate this change in velocity both in the vector form and the magnitude [angle] form to 2 decimal places
