I will use to find the value of acceleration due to gravity.

With a air track and a spring attached to a glider we should find the value of "g".

The track is inclined and with two different equilibria (which are achieved by using two different masses on the glider) we kan determined "g".

g=(4pi[itex]^{2}[/itex][itex]\cdot[/itex]bL)/((T[itex]^{2}[/itex]-t[itex]^{2}[/itex])H)

b = the extension of equilibrium (we got it to 0.026 meters)

L = the length of the track (2 meters)

T= the time of one period with more weights on the glider (2.37 s)

t = the time one period with no extra weights on the glider (2.12 s)

H = the height of the air track (0.184 meters)

If we insert all the values we get 9.939m/s/s.

How should we derive the equation?

If we take the formula of pendulum motion we get g=(4pi[itex]^{2}[/itex][itex]\cdot[/itex]L)/T[itex]^{2}[/itex]

I don't seem to get any further with the equation so I need some help.
