Depends on the rocket. Some rockets use solid fuel, some use liquid.

The book's potential energy is 294 joules.

Just use the formula for potential energy: PE = mgh (potential energy = mass x gravity x height). Use 9.8 for gravity, replace the parts you know, and solve for the unknown position (height).

Use the formula for potential energy: PE = mgh (mass x gravity x height). From this formula, it is clear that the amount of potential energy of an object depends on the object's mass, the force of gravity, and the height above the ground.

PE=mgh (mass x gravity x height). Use 9.8 for gravity. Answer is in joule.

You wont need any energy but, you can still use a rocket.

Renewable energy is gaining more attention because it is cheaper and better for the environment. The continued use of fossil fuels will only increase the amount of pollution in the air, water, and land.

Gravitational potential energy = (weight of the object) x (height) or Potential energy = (mass) x (acceleration of gravity) x (height)

It will have kinetic energy from its velocity, and potential gravitational energy from how high it is above the earth. If it is still being driven by a rocket engine, these amounts of energy will be increasing. If the engine has stopped it is in free flight, and will continue to rise until reaching maximum height and minimum speed, then it will start to pick up speed as it falls. The total energy will be constant once the engine has stopped. Of course in practice air resistance has some effect, some energy will be given up to the air in frictional heating.

You could use other non compressible liquids. You really are using the air trapped in the rocket as the energy source. The water compresses the air to very high levels and then is pushed back out the enf of your rocket.

It is not very likely that solar energy will die out anytime soon. In fact solar energy has been steadily gaining popularity and many people are building off the grid houses that exclusively use solar energy.

You will gain weight if the amount of energy you take in is more than the amount you use.
