2.7 CALC A car is stopped at a traffic light. It then travels along a straight road such that its distance from the light is given by x(i) = br? - cr', where b = 2.40 m/s and c = 0.120 m/s. (a) Calculate the average velocity of the car for the time interval 1 = 0 to 1 = 10.0 s. (b) Calculate the instantaneous velocity of the car at i = 0,1 = 5.0 s, and t = 10.0 s. (c) How long after starting from rest is the car again at rest?
