Question

18. The speed-time graph for a car is shown is Fig. 8.12.
Speed (ms)
8
10
4 6
Time (s)
Fig. 8.12
(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

Answer:

The area under the slope of the speed – time graph gives the distance travelled by an object. 56 full squares and 12 half squares come under the area slope for the time of 4 second. The total area of the squares will give the distance travelled by the car in 4 second. Therefore, car travels 16.53 m in first 4 second.
