Answer:

283,716 J

Step-by-step explanation:

By the conservation law of energy, if there is no air resistance, the energy at the top of its trajectory will be the same that it has at the beginning. There will be potential and no kinetic energy because it won't have velocity but the total energy will be the same.

Then, the energy at the top of its trajectory will be 283,716 J
