1. The problem statement, all variables and given/known data I did an experiment on how stretching a rubber band, affects the range or distance of a projectile shot. Variable list: Independent Variable Amount of stretching Dependent Variable Range or distance I created my catapults on my own and used two different rubbers bands and compared them 2. The attempt at a solution Then I calculated the average, however i wanted to show that there is a linear relationship between the stretch and the range, but i dont know much about it. so can you help in determining whether what i did was right or wrong? Then I graphed the average and produced a line of regression, but it didnt pass through the points so its not linear... Also i wondering whether i can get the potential energy, is it possible?
