Hey micromass, I'll just list some of the bands I'm really interested in : Pink Floyd, Brian Jonestown Massacre, Neil Young, Mac Demarco, Beatles, Metallica, Nirvana.. There are more but these are the ones that popped in my head. What do you listen to?
I would have used it this way:
We know that the potential energy is 0 at the beginning and that at the end of the motion it is 9188 joules. Therefore, by using the law of conservation of energy I would equal the initial kinetic energy to the final potential energy like this -> KEo = PEf ->...
