Problem

During four successive one-second intervals, a toy car moving in a straight line covers

2\,\text{m}

6\,\text{m}

10\,\text{m}

and

14\,\text{m}

respectively. The car starts counting time from

t=0

at the beginning of the first interval. Using this information, answer the following: a. (i) Prepare a table showing the cumulative distance travelled at the end of each second. b. (ii) Draw a distance–time graph for the motion for the first

4\,\text{s}

. c. (iii) From your data, estimate the average speed during each one-second interval and plot an approximate velocity–time graph for the

4\,\text{s}

. d. (iv) State, with reasons based on your graphs, whether the toy car is moving with uniform acceleration.
