A car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by x(t)=bt2−ct3, where b = 3.00 m/s^2 and c = 0.100 m/s^3.
Required:
a. Calculate the average velocity of the car for the time interval t = 0 to t = 8.0 s.
b. Calculate the instantaneous velocity of the car at the following times:
1. t = 0
2. t = 4.0 s
3. t = 8.0 s
c. How long after starting from rest is the car again at rest?
