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
