Q1KinematicsFree sample

Fig. 1.1 shows the distance-time graph for two cyclists A and B. They start a $500\ \text{m}$ race together but finish the race at different times.

Fig. 1.1

(a)

Use Fig. 1.1 to determine

(i)

the distance between A and B at time $t = 20\ \text{s}$ ,

______

(ii)

the difference in the time taken by A and B for the race.

______

(b)

Cyclist C starts the race at the same time as A and B and covers the first $200\ \text{m}$ of the race at a constant speed of $5.0\ \text{m / s}$ . He then accelerates and finishes the race at $t = 60\ \text{s}$ .

(i)

On Fig. 1.1, draw the distance-time graph for cyclist C.

(ii)

Calculate the average speed of cyclist C for the whole race.

speed = ______
