your right.

so the correct calcs would be.

5 tons traveling at 509.116 km/h = 0.5 * 5000 kg* 141.421 * 141.421 ms = 49.999 MJ (50 MJ)

1 ton traveling at 1,138.417 km/h = 0.5 * 1000 kg* 316.227 * 316.227 = 49.999 MJ (50 MJ)

1 kg traveling at 36,000 km/h = 0.5 * 1 kg* 10,000 * 10,000 = 50.00 MJ (50 MJ)

quite a big difference , thanks for pointing that out.

theres plenty of room there to continue with the 10 km/s launch velocity.

3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
