While you’re right, the MTOW of a B-26 is around 17 tons, the 767 is 150-200 tons.
So there is a factor of around 10 between them, so if the 767 flies 3 times as fast - which it doesn’t, the B-26 cruises at more than 0.35 Mach at close to sea level, and the 767 is not supersonic - that means that the factor from the speed can’t be more than about 3 squared, so 9.
So the factors from the weight and the speed are roughly equal IMO.
Speed matters more than mass when calculating kinetic energy.
Are you sure about that? An air rifle shooting supersonic aluminum pellets has considerably less kinetic energy than a .22 LR bullet, because of the weight of the bullet. Some air rifles actually shoot their projectile faster than a .22, but they have like 10x less energy upon impact.
Speed matters more than mass when calculating kinetic energy. A 767 is much, much faster than a B-25.
