Fig. 1.1 shows the speed-time graph for a vehicle accelerating from rest.

(a)Calculate the acceleration of the vehicle at time t = 30 s.

Fig. 1.1 — see the question text for what it shows
Answer guidance

Calculate Show your working. The method can earn marks even when the final value is wrong, and a bare answer often cannot.

[3 marks]

Without further calculation, state how the acceleration at time t = 100 s compares to the acceleration at time t = 10 s.

(b)Using ideas about forces, explain why any change in the acceleration has occurred.

Answer guidance

Using You must use the thing it names. An answer that reaches the right value another way may not score.

[2 marks]

(c)Determine the distance travelled by the vehicle between time t = 120 s and time t = 160 s.

Answer guidance

Determine Work it out from what you are given or from the figure, and show how you got there.
