Part 1 A: start back, wait, move forward, stop B: start walking back at a constant speed, stop, then walk forwards at a constant speed Part 2 A: Start close, wait, steady movement away B: Start moving away at a constant speed, stop, move forward at a constant speed C: Movement away at a constant speed D:Start back and immediately move forward slowing down, then moving away at an increasing speed 3. movement away with a constant increase in velocity Story 2-Floor (5.7 m) Story 3-Story 2(3.7 m) total (9.4 m)

Unformatted text preview: trial 3 1.01s 1.41s 1.63s tiral 4 1.07s 1.5s 1.72s average 1.07s 1.42s 1.8s The two graphs are relatively linear. This means that the height of the drop is positively correlated to the time it takes for the ball to hit the ground. When comparing the red and blue plots, the red plot (time vs (1/2)gt^2) has a slightly higher slope than the blue (time vs height). Furthermore, the tennis balls fall best matched its y=(1/2gt^2) plot when compared to the Wiffle ball. Slope (m) = 1.2825 0.755875=(1.2825)(0.045323)+b b=13.004 y=13.004t^(1.2825) The tennis ball having a larger mass has a more linear plot. This shows that the air resistance may not be as significant on the tennis ball as it is on the wiffle ball....
