I need to find the acceleration of gravity in my area (I live 287 meters above sea level.)(adsbygoogle = window.adsbygoogle || []).push({});

I know that y = 0.5*g*t^{2}, y=(v_{2}^{2}-v_{1}^{2})/2*g, f_{g}=m*g, and F= G*m_{1}*m_{2}/d^2

I placed a ramp at an arbitrary angle. I found the height of the ramp, the angle of the ramp, and the length of the ramp.

I placed a cart on the ramp and let it run down to the end of the ramp, timing the whole trip.

I've got all this data and I'm not sure how I would calculate g, for it is a vertical force and my ramp is somewhere in-between 90 and 45 degrees.

(I have messed around with trig. but got no where).

You see I haven't given you all of the data, I'm not looking for the exact answer I just need a general statement on how to find g in this situation.

My teacher gave me a hint, he said to "extrapolate."
