Part 3. (1 point) In this part of the experiment each student measures the time it takes for the glider to travel a distance Ax down the plane. We do this by using the photogate timers. The distance between the photogates can be easily changed by just moving them farther apart for each new Ax. Since each student measures the time it takes twice we have a total of six times for each Ax distance. The distance the glider travels between the photogate timers is changed from zero, 0.25m, 0.50m, 0.75m, 1.0m, 1.25m, 1.50m and finally 1.60 meters. In the table fill in the missing columns for the average time tavo by adding the six times together and then divide by 6. Then complete the last column by taking the average time squared and divide by 2. We will use these values later in a graph.
