1. The problem statement, all variables and given/known data The object of the lab is to find the diameter of the bouncing ball shown in the pdf attached. We are working with Logger Pro. The only 2 pieces of information that we have is that the ball is on the surface of the earth, where Ay=-9.81 m/s2, and that the frames are 0.05 seconds apart. This does not seem like anywhere enough information to go on, since that is all the information. 2. Relevant equations I do not know where to begin this problem. I'm not sure how I could get to the end. 3. The attempt at a solution I've tried to reason this out, but I do not see a way that, from this little info, we can achieve the diameter of the ball. Though I could track the ball on Logger Pro, and make a graph of its path, I do not see how this will do me any good. I do apologize for the lack of work, but I am truly stumped and lost on how to even begin on this problem. I suppose that's why my teacher called it a "challenge" lab.
