Conservation of energy
** **
In the space below report, one trial to a line in comma-delimited format, the acceleration up and the acceleration down the incline, and the difference in these accelerations. Beginning in the sixth line explain how you determined your accelerations from the given data. Be sure your explanation connects your determination of acceleration result to the initial data, and be sure to include an explanation of the algebra of the units, and include a sample calculation for one of your trials.
----->>>> accel up, down 5 trials
Your answer (start in the next line):
Part of the Conservation of energy on an incline

I just don't see how to get acceleration from the information we have aquired so thats what I'm asking can you tell me or point me in the right direction

How do I find acceleration from what we have
@&
I don't see the information on which you are asked to base your calculation, so I can't be sure I'm answering your question. However I think the following should cover it. Let me know if not.
Presumably you have found the time required to travel up the incline and measured the distance. So you know `dt and `ds. You also know that vf = 0, since you measured the time interval from the initial instant until the ball came to rest, just before it began to accelerate back down the incline.
Similarly you will have data that allows you to determine how long it took the ball to roll back to its original position, and can use that data to find its acceleration down the incline.
