1.1. A car, initially at rest, begins to move with an acceleration of 1.5 m s^–2. 

Calculate the speed of the motor car after 20 s.

1.2. Calculate the distance travelled by the motor car in the first 10 s of the motion.

1.3. Calculate the distance travelled by the motor car in the first 20 s of the motion.

1.4. Figure 1 shows the graph of acceleration against time together with two incomplete sets of axes.

Figure 1

Sketch on these axes the corresponding graphs of speed and distance travelled for the first 20 seconds of the car’s motion. 

You should include labels for the axes and any known numerical values.
