one of my groups failures was that on one of the trials the bear hit the ground pretty hard probable because the stretch of the cord was a little bit high
what my group could of done differently is re-measure and account for all the variables so that the calculations would be precise
what my group learned from this engineering design challenge was how to apply some of the equations for springs to actual springs.
my group recommends for students doing this challenge in the future is to not get to attached to bungee bear since he does die pretty often and to aim higher to avoid hitting the ground.
my group would change the point amounts for being close to the ground in the successful criteria so that you could still get good amount of points well being safe from ground.
