Hey everybody. We have this extra credit project due friday. The conditions are as such: We use a 3 meter string and hang 4masses on it with the distance being no less that .5m apart. We can use masses in variations of 50kg, but he suggested we use all 100kg masses. We drop the string from a 3rd floor window, and the sound of the masses hitting the ground is measured versus time. We use that graph with a program called graphical analysis, and we must achieve a correlation of 98% with a straight line. Put simply, the time between the sound of each one hitting must be about constant. I'm not really sure about anything else. We are allowed to use sources such as this fine forum, so I'm thankful for that. What suggestions do you guys have? Thank you in advance. Love you guys. Now, my idea was to have the masses arranged so that there is a smaller distance between the ones that will be hitting first and a larger between the last ones.
