Question

(a) A student is shown a video of a ball being dropped next to a long piece of measuring tape.  The student imagines the origin to be located at the ball’s initial location, when t = 0, and records the list of positions shown in the table below.  The time between each measurement of position is 0.10 s, as determined by watching the time signature on the video.

Complete the following table by computing the average velocity between each set of subsequent positions, and then computing the average acceleration between each set of subsequent average velocities.

(m) 0.00 -0.05 -0.18 -0.45 -0.83 -1.21 -1.78 -2.47 -3.25 -4.02 -5.01 -6.07
(b) Evaluate your average acceleration data.  Was this likely a video of a ball falling in Earth’s gravitational field? Explain your conclusion.
