Homework Statement
A block with mass m is attached to the end of a spring with a constant spring k. It oscillates with a period of 2 seconds when pulled. When an additional 2 kg is add to the block it oscillates with a new period of 3 seconds. What is the mass of the black and the spring constant K?
Homework Equations
T = 2pi*sqrt (m+2/k) my apologies for the format. The symbols will not post for some reason.
The Attempt at a Solution
I attempted to use the about equation above and solve for m. Of course I ran into the problem that I do not know the spring constant k as well. I tried to find K by use the equation and solving for k by imputting the mass of the second block. However I am not confident because the period T at 3 seconds is when the masses are added together and not just for the 2 kg mass alone.
I am fine with the algrebra if I can just start the equation. Any help would be greatly appreciated.
