the height from centimeters to meters. Y Pendulum Average: 11.6 cm = 0.116 m 8. By using the mass and the average height, I had to find the initial velocity ( V 0 ) of the steel ball.

9. After finding the initial velocity, I had to find the time it took to launch the ball and then use that to find the distance horizontally ( ∆ X ¿ for the next experiment to predict where the steel ball will land.
10. I had to measure 2.7 m from the ballistic pendulum to the place the steel ball would be launched. 11. I had to then tap a paper there and mark 2.7 m on the paper. 12. I had to launch the steel ball ten times at the paper and mark the length on the paper where the ball was launched. 13. I had to find the average and then convert it into meters. 14. I had to then find the percent error and compare the experimental value to the accepted value. Conclusion: My hypothesis was correct because my initial velocity from the experiment was really close to the accepted value. The steel ball was launched almost spot on to the predicted value from the calculations. All of the values were close to 2.7 meters. For this lab, the percent of error was not that much. I only had 2.59% of error which is not that much compared to other labs. Some source of error could have happened when my group was measuring the height because there could have been some changes of number in the height by reading it wrong.

### What students are saying

• 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.
