Question

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

1. 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.
2. Which part of the graph represents uniform motion of the car?

Answer 1

(a)

The shaded area which is equal to $\frac{1 }{ 2} \times 4 \times 6 = 12 \;m$ 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.
