Make a rough sketch showing how the following properties of a baseball depend on time, from the moment it is hit high into left field to the time it is caught by the outfielder. You may neglect the effects of friction!
1. Kinetic Energy
2. Potential Energy
3. Totall energy
* should be three separate graphs.
4. How would friction change the above results. Make sure an average baseball fan can understand you
