My guess is that is not the ideal. Seems better to spread the vertical impulse by landing the wheels one at a time.

No, that's a Megajoule. A Gigajoule has nine zeroes. But the 275kWh is correct (well, 278).

Ok, but the force at point O due to the suspended weight is W, as you had it in post #98. The error there is that, since the horizontal...

That gives the right moments equation, but it is not right as a force diagram. The weight W, applied where it is, is not equivalent to...

@gleem is taking moments about P, not O. I see no conflict.

How come you have relocated W to act at point O? The horizontal distance from P to the hanging mass is what matters.
