1. The problem statement, all variables and given/known data I did an experiment in which I bounced a ball under a motion sensor. From that I got a generated graph on the computer in the shape of a parabola. The max height of the ball at each interval was also obtained from looking at the graph. From the maximum height values, I calculated the maximum potential energy per unit mass (U/m) of the ball in the middle of each interval. So for max height for the first interval I got: U = (9.8 m/s^2)(0.686 m) = 6.733 m2/s2 (U/m) for the second one I got 4.939 U/m and the third one I got 3.685 U/m. My question is: determine the amount of mechanical energy (per unit mass) that the ball loses during the three selected impacts with the ground 2. Relevant equations 3. The attempt at a solution I know that U/m (potential energy) is equal to E/m (mechanical energy) of the ball when it is in free flight but I'm not sure how to find the mechanical energy lost between bounces....do I just subtract the values and the difference is the loss? Thanks in advance!
