A sample set of graphical data for one of the trials is shown.

No graphical analysis is required; only numerical.

Trial	Spring Constant (N/m)	Amplitude (m)	Mass (kg)	Speed (m/s)
1	1.35	0.10	0.25	0.23
2	1.35	0.20	0.25	0.45
3	1.35	0.30	0.25	0.68
4	1.35	0.40	0.25	0.90
5	1.35	0.50	0.25	1.13

Analysis: [Use the experimental data contained in the data table above to complete an analysis. Determine if energy is conserved. Clearly show which data was used and what calculations were done to compare the kinetic energy and elastic potential energy.]

you would use this formula-Ek= 1/2 mv2 and Us=1/2kx2
