height as the tray. Pace a carbon paper on top of the tray. Launch the ball 5 times.  Measure the horizontal range R from the launcher to the point of impact for all 5  launches. Then take the average. Calculate v 0  using  θ 0 , R, and y = 0. Record data in table  III.  Measure the height H the launcher is from the floor. Calculate distance D the ball  will hit the ground at using  θ 0 , y = -H, and v 0 . Show calculations on a separate sheet.  Release the ball from the launcher again, measure the distance the ball strikes the ground  using carbon paper, and find percent difference between actual distance and theoretical  distance. Record results in table IV.

Discussion: 1. How close is your prediction with the experimental result? What could be the  factors that cause the errors? How to improve it? Our experimental result was less than 10% different than the theoretical result and  therefore was quite close to our prediction. Factors that may have caused this difference  could be rounding in measurements and lack of attention to the clicks of the Mini  Launcher. To improve results, make sure to hear the specified clicks you are  experimenting in from the launcher and be as precise in your calculations as possible. 2. What shape is the path of the projectile? The path of the projectile is an arc-shaped path. It rises to a certain point and drops down  due to gravity, making the shape look like an arc-like curve. Conclusion: In doing this experiment I learned how to calculate projectile motion through linear  motion equations to predict two-dimensional problems. It is possible to approximate at  what distance a ball will strike the ground through these calculations and which will be  helpful tool. This lab taught me that everything is fixed and that it is possible to predict  the outcome of a motion.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
