Analysis The video you captured for the projectile motion can be analyzed using Tracker software as you did in Lab 2. However, you are now interested in both the m and 3; components of the ball's position as a function of time. After importing your video, pause it at the moment just after the ball loses contact with your hands, and set the time to zero. Then, set the length scale and drag the axes origin to the centre of the ball. Show the graph presenting the relation between the ball's vertical position (3;) and the time (t) and perform a parabolic best t of the form y = A*t"2 + B*t + C. Also, show the graphical relation between the horizontal position (so) and the time (t) and perform a linear t of the form x = A*t + B. Finally, show a graph of the projectile's trajectory (y vs. :3). Do not forget to take snapshots of the relevant subwindows to include in the lab report. Interpret the meaning of the t parameters that describe the projectile's motion in each direction. Do your data support the assumption that the ball moves at a constant acceleration in the vertical direction? Do your data support the assumption that the ball moves at a constant velocity in the horizontal direction? Provide sufficient discussion in this regard based on your experimental data. Make sure to comment on the limitations of your experiment and possible causes for measurement uncertainty. ++
