When different loads are placed on the spring from the previous problem and the system is allowed to oscillate, you find the following period vs load data.

What value of the spring constant would you derive from this data in N/m, to four significant figures?

What fraction of the spring must also be oscillating to two significant figures?

Note that the mass of the spring is 0.5765 kg.

Load (kg)	Period (s)
0.100	0.63128
0.150	0.74043
0.200	0.85503
0.250	0.93181
0.300	1.01353
