If you have 1.0 gallon of gasoline, each of which stores approximately 100 megaJoules of chemical energy, which is released by burning the gasoline, then if you could convert all that potential energy to the kinetic energy of a rocket of mass 30 kg, how fast would that rocket be traveling? If you could convert all that energy to gravitational potential energy, how high could you fire the rocket?
(Note: Do not ever even think about trying to build a gasoline-powered rocket unless you want to spend the rest of your life in a burn unit, provided you even survive.)© BrainMass Inc. brainmass.com October 10, 2019, 2:50 am ad1c9bdddf
