Question 3

A car starts from rest and accelerates uniformly for 12 seconds until it reaches a speed of 24 m s−1^{-1}−1.

It travels at this constant speed for 20 seconds and then decelerates uniformly at 3 m s−2^{-2}−2 until it comes to rest.

a.

Find the displacement of the car from its starting point at the end of each of the three stages of its motion.

[3]
b.

Sketch a displacement-time graph for the complete motion. Mark on your graph the times and displacements found in part (a).
