A car runs at a constant speed of 15m/s for 200s and then accelerates uniformly to a speed of 25m/s over a period of 20s. this speed is maintained for 3000s before the car is brought to rest with uniform deceleration in 30s
Draw the velocity time graph to represent the journey describe above from the graph calculate
i. The acceleration while the velocity change from 15m/s
ii. The total distance travelled in the time described
iii. The average speed over the time described?
