b. Describe what happens to the velocity vector as the car goes forward and then returns to 0.00 m.
c. From the Position vs. Time graph, read the furthest distance the car reaches from the starting point.
d. From the Position vs. Time graph, what is the time that the car reaches this furthest distance?
e. Using the time you found in the previous question and looking at the Velocity vs. Time graph, what is the velocity at this time?
f. Using the time you found above and looking at the Acceleration vs. Time graph, what is the acceleration at this time?
g. Considering your last two answers, is it possible for an object to have zero velocity while at them same time having a nonzero acceleration?
