The Acceleration Due To Gravity

[Snake]

I have this lab. I have all the data but I need help w/ the analysis. How would I answer number one?

Well I think you were suppose to calculate the acceleration using the data given. You have the distance traveled and the time so you just plug Y and t in to determine gravity. You already put gravity in the equation when you were suppose to calculate it.

By question 1, do you mean determine the acceleration of gravity?

If one has distance and time, and one uses y = 1/2 a t2, then

a = 2y/t2

I remember doing this lab back in intro to mechanics.... im sure we found a way to screw up gravity.... wait no no... we had exaaaaaaaaaaaactly 9.8....whaever the rest of the numbers are for 5 digits. Of course, then we realized we had accidently thrown in gravity somewhere and the calculation was circular logic.
