Describe what happens to the velocity vector as the car goes forward and then returns to 0.00 m.
The velocity vector decreases until it gets to 25 m; it then changes direction and increases to the left.

A car starts at position with an initial velocity of 3.8 m/s and an acceleration of 0 m/s2. What is its position when
the elapsed time is 6.5 s? (Please be sure to include units in your answer. Express your answer to one decimal point.)

The velocity vector decreases until it gets to 25 m; it then changes direction and decreases to the left.

The velocity vector does not change length.

From the Position vs. Time graph, read the furthest distance the car reaches from the starting point.

From the Position vs. Time graph, what is the time that the car reaches this furthest distance?

Using the time you found in the previous question and looking at the Velocity vs. Time graph, what is the velocity at
this time?

Using the time you found above and looking at the Acceleration vs. Time graph, what is the acceleration at this
time?

Considering your last two answers, is it possible for an object to have zero velocity while at the same time having a
nonzero acceleration?

Yes
