a car runs at a constant speed of 15m/s for 300s and then accelerate uniformly to a speed of 25m/s over a period of 20s . this speed is maintained for 300s before the car is brought to rest with uniform deceleration in 30s .draw a velocity time graph to represent the journey described above from the graph find the acceleration why the velocity changes from 15m/s to 25m/s ,the total distance travelled on the time described ,the average speed over the time described?
