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.
