3. Ms. Lenarcic is riding her bike at 7.5 m/s [N] to get to KSS when she sees a school bus ahead. She slows down to 3.0 m/s [N] in 20 s. She continues at this pace until the school bus turns down another street 14 s later. a) Sketch a velocity-time graph for the problem. [3 marks] b) Using the graph you drew in Part (a), determine Ms. Lenarcic's displacement between the instant she saw the bus and the instant the bus turns. [3 marks] 3.
