Question

The speed – time graph for a car is shown in Figure:

(a) Find how far does the car travel in the first 4 seconds. Shade the area on the graph that represents the distance travelled by the car during the period. (b) Which part of the graph represents uniform motion of the car?

Answer

(a) Distance covered = area under speed – time

⇒ Distnce = 1/2 × 4 × 6 = 12 m

Shaded area representing the distance travelled is as follows:

(b) After 6 seconds the car moves in uniform motion (at a speed of 6 m/s).
