b) See the graph below.
Work Step by Step
a)
We need to find the time and position of the car in each frame.
1- $\rm (0\;s,1200\;m)$
2- $\rm (10\;s,980\;m)$
3- $\rm (20\;s,830\;m)$
4- $\rm (30\;s,750\;m)$
5- $\rm (40\;s,700\;m)$
6- $\rm (50\;s,650\;m)$
7- $\rm (60\;s,600\;m)$
8- $\rm (70\;s,500\;m)$
9- $\rm (80\;s,300\;m)$
10- $\rm (90\;s,0\;m)$
b) The position-time graph:
