A student investigates the motion of a toy car down a smooth inclined plane using a ticker timer that marks at 0.02 s intervals. The car starts from rest at the top of the plane. The distance between successive dots is measured with a ruler. The data for the first six intervals are recorded in the table below. | Interval (n) | Distance between successive dots (cm) | |--------------|---------------------------------------| | 1 | 1.2 | | 2 | 2.0 | | 3 | 3.0 | | 4 | 4.2 | | 5 | 5.6 | | 6 | 7.2 | Using this data, answer the following questions.

Question Parts

( a )
Calculate the average speed of the car during each 0.02 s interval for the first six intervals. Show the calculation for interval 3 as an example.
( b )
Describe the shape of the distance‑time graph that would be obtained from the data and explain what this shape indicates about the car’s motion.
( c )
Using the speeds obtained in part (a), estimate the acceleration of the car. State clearly the method you use.
( d )
Identify two possible sources of error in this experiment and suggest one way to minimise each.
