1. The problem statement, all variables and given/known data I have a graph of time squared vs. height. It shows the relationship between the height of a ball and how long it takes for it to fall, squared. I don't have this in the form of a question, but I need to use the slope, which is 0.211 s^2/m, and turn it into a value for acceleration to compare it to the gravitational acceleration. I have no clue how to do this. I did 0.459s/m.. I don't know if that's correct. But I need m/s^2. I have an equation for gravity from a pendulum but I don't think that's what I should use. 2. Relevant equations I don't have any equations.. 3. The attempt at a solution I got the square root of the seconds squared to get 0.459s/m but I'm not sure if I did that correctly. Pleaaasse Help. Please.
