A model rocket has just launched and its engine should continue burning for 30 more seconds sending the rocket to a height of 1000 feet. What types of energy does it have?
The rockets engine is fuel or chemical energy which is stored energy, as the engine burns it causes movement (kinetic energy) plus it still has potential to keep burning, so kinetic plus potential energy is mechanical energy.
