A train travels along a straight level track between two stations A and B. It starts from rest at station A and accelerates to a velocity of 24m/s-1 in 12 seconds. The train then remains at this velocity for 2400meters and then decelerates, coming to rest at station B after 8 seconds.

How would I sketch the velocity time graph for the journey?

1) Find the rate of acceleration
2)The rate of deceleration
3)The total distance traveled
4)The average speed for the complete journey

Something like fig 3 in

Have a read and post any questions you have.

Make sure you understand what:
* constant velocity
* constant acceleration
* constant deceleration
Means in terms of sketching velocity time graphs. Also what are the initial and final velocities.
