Fig. 1.1 shows the axes used for distance-time graphs. On Fig. 1.1, sketch graphs for an object that is (i) travelling at constant speed, labelling the graph A, (ii) travelling at decreasing speed, labelling the graph B.
(b)[2]
Fig. 1.2 shows the axes used for speed-time graphs. On Fig. 1.2, sketch graphs for an object that is (i) accelerating at a constant rate, labelling the graph S, (ii) accelerating at an increasing rate, labelling the graph T.
(c)[4]
With the information below, calculate the take-off speed of the plane. Ignore any resistive forces. constant forward force = 56 000 N; mass of plane = 16 000 kg; time of travel along runway = 16 s.
