Question

The speed-time graph for a car is shown is Fig.

(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 1

(a) The shaded area which is equal to 1/2 x 4 x 6 = 12 m represents the distance travelled by the car in the first 4 s.

(b) The part of the graph in red colour between time 6 s to 10 s represents uniform motion of the car.
