1. The problem statement, all variables and given/known data 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) = bt^2 - ct^3, where b = 2.40 m/s^2 and c = 0.100 m/s^3. 1. Calculate the average velocity of the car for the time interval t = 0 to t = 10.0 s. 2. Calculate the instantaneous velocity of the car at t=0s. 3. Calculate the instantaneous velocity of the car at t=5.00 s. 4. Calculate the instantaneous velocity of the car at t=10.0 s. 5. How long after starting from rest is the car again at rest? 2. Relevant equations x2-1/t2-t1 3. The attempt at a solution 1. I was wondering what the x-values were since I think change in time is just x2-x1/10.0 seconds. 2,3,and 4, do I just plug t into the equation bt^2 - ct^3? 5. No idea.
