Part C: Thinking kills A car (C) and a van (V) are stopped beside each other at a red light. When the light turns green, the vehicles accel- erate with the motion depicted in Figure 19. 20 7 15 C v (m/s [SD) 10 5 30 60 90 120 150 180 220 (s) Figure 19 Velocity-time graph of the motions of two vehicles (a) At what instant after the light turns green do C and V have the same velocity? (b) At what instant after the light turns green does V over- take C? (Hint: Their displacements must be equal at that instant.) (e) Determine the displacement from the intersection when V overtakes C
