Fig. 1.1 shows the speed-time graph for a vehicle accelerating from rest.
Calculate the acceleration of the vehicle at time t = 30 s.
Calculate Show your working. The method can earn marks even when the final value is wrong, and a bare answer often cannot.

Fig. 1.1 shows the speed-time graph for a vehicle accelerating from rest.
Without further calculation, state how the acceleration at time t = 100 s compares to the acceleration at time t = 10 s.
Using ideas about forces, explain why any change in the acceleration has occurred.
Using You must use the thing it names. An answer that reaches the right value another way may not score.
