DATA AND RESULTS
Mass of Ball: .059 kg
| Trial | Initial Height (yi) | Final return height (yr) | Time to ground | Time to return |
| 1 | 4 m | 2.2 m | .882 s | .644 s |
| 2 | 3.5 m | 2 m | .830 | .615 s |
| 3 | 3 m | 1.7 m | .772 s | .561 s |
1. The potential energy of the object at its highest point_2.32_Trial #1
2. The kinetic energy of the object just before impact _2.32_
3. The velocity of the object just before impact, using kineticenergy _8.87 _
4. The “kinetic energy” of the object just after impact _33.80_(Hint: neglect air resistance and think about the height itrebounds to)
5. The “rebound” velocity of the object _10.62_
6. The loss in energy _0 + 2.32 = 33.80 + 0 + loss_
Trial #2
1. The potential energy of the object at its highest point_2.03_
