7.7 Work out change in speed of ball

Change in speed: Rolling ball experiment

Here is the table to record the data of the experiment. Repeat the experiment as many times as needed to be able to record the time for each segment of 30 cm for at least four different runs.

Segment	Time t for 1st run (s)	Time t for 2nd run (s)	Time t for 3rd run (s)	Time t for 4th run (s)	Average time (s)	Average Speed (cm/s)
0-30 cm
30-60 cm
60-90 cm
90-120 cm
120-150 cm
