1. . Figure below shows the idealized motion of a car. a) Determine the average speed between 4.0 s and 8.0 s; and between 0.0 s and 8.0 s. b) Calculate the average velocity between 8.0 s and 9.0 s; between 12 s and 16 s; and between 0.0 s and 16 s. c) Find the instantaneous speed at 6.0 s and 9.0 s. d) Calculate the instantaneous velocity at 14 5. 50 30 d (m [ED) 20 10 4.0 8.0 12 16 1 (s) 2. A car (C) and a van (V) are stopped beside each other at a red light. When the light turns green, the vehicles accelerate with the motion depicted in Figure below 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 overtake C? c) Determine the displacement from the intersection when V overtakes C 20 15 C v (m/s [SD) 10 5 30 60 90 120 150 180 220 t (s)
