Contributions to Project 1

    For the first part of this project, I modeled projectile motion using Video Analysis and then calculated the uncertainty of the range and initial velocity. Then I found the average spring constant with uncertainty by using multiple masses to stretch the rubber band.  I used the average spring constant to calculate the initial velocity using a Work-Energy equation. Next, I found the max height of the rocket launched at a 90 degree angle by doing 2 trials. I used these measurements to find the initial velocity using a different Work-Energy equation. I combined all of these values into one table that showed each initial velocity using a certain stretch. I made graphs of both of these initial velocities vs. stretch. I then helped to start writing the basic code of the projectile motion. As we progressed, I calculated the value for "C" (using the spring Work-Energy equation) to accurately compute the initial velocity in the code. After the code was finished, I helped to start and finish the project slides. Overall I believe all of my group mates did equal and accurate work to complete our project.
