Solve a,b,c and d

3. A bus leaves the school at (B), @) and travels west at a speed of 10A) (ex. 20) km/h for @ hours. Then, it turns to travels north at a speed of 10@ km/h for @ hours. East = positive x and North = positive y. a) Paste a Google slides screenshot or a sketch on a paper: 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 33.440 N]", 2 decimal places c) Paste a Google slides screenshot or a sketch on a paper: Sketch the two velocity vectors to scale, As the car turns in the middle of the journey, draw the change in its velocity vector. Hint: The change from one vector to the other is also a vector. Change is "A", the same kind of "A" in Calculus. d) Calculate this change in velocity both in the vector form and the magnitude [angle] form to 2 decimal places
