b. Figure 5 in the lab manual shows the apparatus we will be using. For a given height,
you will be dropping the ball multiple times.
Figure 4 shows the case where the photogate is not properly centered on the tube.

Figure 4 - Apparatus when the photogate is off-center.
If the photogate is not properly centered on the tube for our set of trials, this
would result in measurements of the ball's speed that would
a. Be systematically lower than the true value.
b. Be systematically higher than the true value.
c. Vary randomly about the true value.
ii. Briefly explain your answer.
