Acceleration / deceleration

A car accelerates at a steady rate from 0 to 108km per hour in 30 seconds, travels at constant speed for one minute, and then brakes at a constant rate to a stop in 10 seconds.

Please answer the following questions with full explanations:

1) Draw a velocity-time graph with velocity (vertical axis) in m/s and time (horizontal axis) in seconds.

2) Calculate the acceleration in the first 30 seconds, and the deceleration in the last 10 seconds.

3) Calculate the distance travelled in each section of the motion.

4) Sketch a distance-time graph for the motion.

Thankyou
