Finding mass of an object on a spring, given Frequency

[QUOTE="Zach_Sch, post: 5440956, member: 590201"] [h2]Homework Statement [/h2] A mass m at the end of a spring oscillates with a frequency of 0.84 Hz . When an additional 730 g mass is added to m, the frequency is 0.65 Hz . [h2]Homework Equations[/h2] f*2pi = w w = (k/m)^1/2 f = (1/2pi)*(k/m)^1/2 [h2]The Attempt at a Solution[/h2] I simply used the third equation twice, rearranging to the following: m = k/(2pi*f)^2 using this equation two different times I ended up with: m = k / (2pi*.84)^2 m + .73 = k / (2pi*.65)^2 I solved the above equations for m and came out with the wrong answer. Any help is greatly appreciated! Thanks in advance : ) [/QUOTE]
