Change in speed: Running Race Activity

\r\n\r\n

\r\n

Collate data of the running race activity and calculate the average speed of the runner.This will give you an insight whether the speed of runner is uniform or non-uniform throughout the race and if there is any variation of speed through the various segments.

Hope all of you have looked at your data. Now let us reflect on the following questions before moving ahead.

\r\n\r\n

\r\n
Did you take same time to run each segment?
\r\n
\r\nWas your run uniform or non-uniform?

You can use the following equation to calculate the average speed,
\r\n
\r\n \$\\Delta V = {d_1 - d_0 \\over t_1 -t_0}\$

\r\nDo not forget to write the unit of speed.
