Problem: If all the energy contained in a 46 gram golf ball could be used how long could it power one 100 watt light bulb?
You must show your work in an efficient manner so I can understand it in clearly. Thank you.
Two particles, each of mass M, are hung between three identical springs. Each spring is massless and has spring constant K. Neglect gravity. The masses are connected as shown to a dashpot of negligible mass.
