1)
Without changing any of the settings, run the simulation a few times by clicking the "run again" button in the physlet window and observe the graphs. In the box below this question answer the following questions: A. How do the components of the initial velocity v_{o} determine how long the projectile will be in the air? B. How do they determine the range x - x_{o} of the projectile?
2) Change the x-component of v_{o} to 4 m/s. Click the "try it" button and observe the simulation and the graphs.
In a few sentences explain the changes you observe in the graphs.
3) Change the y-component of v_{o} to 8 m/s. Click the "try it" button and observe the simulation and the graphs.
4) If you wanted to find an expression for y in terms of x, what equations would you start with, and how would you proceed?
