4.4.2. Exercise: Plotting a series 2#

Using a video camera, you recorded the position of a sprinter each 2 seconds. The recorded data are:

t = [0.0, 2.0, 4.0, 6.0, 8.0, 10.0, 12.0, 14.0, 16.0, 18.0, 20.0]  # seconds
p = [0.0, 8.9, 28.0, 45.2, 60.4, 67.4, 75.5, 86.2, 93.0, 95.3, 100.0]  # meters

You also used five timing gates placed at positions 0m, 25m, 50m, 75m and 100m. The time recorded by these timing gates are:

timing_gates_time = [0.0, 2.65, 5.70, 10.25, 20.0]

Write a code that produces this figure:
