Question

FIGURE EX1.18 shows the motion diagram of a drag racer. The camera took one frame every 2 s.

a. Measure the x-value of the racer at each dot. List your data in a table similar to Table 1.1, showing each position and the time at which it occurred.

b. Make a position-versus-time graph for the drag racer. Because you have data only at certain instants, your graph should consist of dots that are not connected.

Short answer

A table having data of the position and time of a drag racer should be mentioned at a time interval of $2s$and using these data a position-time curve of the same is to be mentioned.

Step-by-step solution

Part a; Step 1: Introduction

A motion diagram of a drag racer is given in the question.

The camera takes the frame in every $2s.$

A table showing position of the drag racer with time need to be created.

Position-time table

A table of position of the drag racer with respect to time is shown here:

Number of dots	Time (s)	Position (m)
1	0	0
2	2	25
3	4	95
4	6	215
5	8	400
6	10	510
7	12	600
8	14	680
9	16	720

Part b; Step 1: Introduction

Motion diagram of a drag racer is shown here.

We have to create a position-time graph using the information given the the motion diagram.

Position-time curve

A position-time graph of the drag racer is given below according to the data in the above mentioned table:
