A. How does part 1 of the graph compare to part 2?

b. How does part 8 of the graph compare
to part 9?

C. What is significant about parts 3, 5,
and 7?

d. What is the difference between part 4
and part 6?

We have the graph of position vs time (as you know, the derivatives of this graph are equivalent to the velocity, so the slope in each part of the graph is equal to the velocity of the car in that part, as steeper is the slope, larger is the velocity, and if the slope is positive, the velocity is positive, if the slope is negative, the velocity is negative)

A) Part 1 and part 2.

You can see that part 1 is a bit steeper than part 2, this means that in part 1 the velocity of the car is larger than in part 2.

B) Part 8 and part 9.

You can see that part 9 is steeper than part 8, meaning that the speed is larger in part 9 (in both parts the velocity is negative)

C) part 3, part 5 and part 7.

In these 3 parts we have a line parallel to the x-axis, this means that the velocity is zero in those 3 parts, but the position is different.

D) part 4 and part 6.

Part 4 is steeper than part 6, and part 4 has a positive slope while part 6 has a negative slope.

So the speed in part 4 is larger, and the sign of the velocity is different in each part, in part 4 we have positive velocity and in part 6 we have negative velocity.
