Figure 1 shows the speed-time graph for the journey of a car moving in a long queue of traffic on a straight horizontal road.
At time \(\mathrm { t } = 0\), the car is at rest at the point A .
The car then accelerates uniformly for 5 seconds until it reaches a speed of \(5 \mathrm {~m} \mathrm {~s} ^ { - 1 }\)
For the next 15 seconds the car travels at a constant speed of \(5 \mathrm {~m} \mathrm {~s} ^ { - 1 }\)
The car then decelerates uniformly until it comes to rest at the point B.
The total journey time is 30 seconds.
- Find the distance AB .
- Sketch a distance-time graph for the journey of the car from A to B .
