11. A pedestrian is running at his maximum speed of 8.00 m/s to catch a bus stopped by a traffic light. When he is 24.0 metres from the bus, the light changes and the bus accelerates uniformly at 0.800 m/s2. (a2/5) Sketch a position vs time graph for the pedestrian and the bus. (b3/5) Find either how far the pedestrian must run to catch the bus or his "frustration distance" (closest approach).
