Neco Model Questions Vol1 2017 Physics Question 3

A student investigates the motion of a steel ball falling freely using a ticker timer that marks at a frequency of 50 Hz (i.e. one tick every 0.02 s). The ball is released from rest at the top of a vertical track. The distances measured from the release point after each successive tick are given in the table below. | Tick (n) | Distance from release point (cm) | |----------|----------------------------------| | 1 | 0.2 | | 2 | 0.8 | | 3 | 1.8 | | 4 | 3.1 | | 5 | 4.9 | | 6 | 7.1 | | 7 | 9.8 | | 8 | 12.5 | | 9 | 15.9 | |10 | 19.6 | Using the data, the student is required to analyse the motion of the ball.
