[QUOTE="OmCheeto, post: 6832414, member: 103343"] How about laying on your back on a skateboard?

It went on for 2 years! I just thumbed through it and I'm not sure anyone came up with a definitive answer. The math involved is apparently so peculiar that even [URL='https://www.physicsforums.com/threads/why-a-man-on-the-moon-can-jump-21-times-higher-than-on-the-earth.774140/post-4871663'][B][I][U]Dale initially boogered it[/U][/I][/B][/URL]. I've been here 15 years and have NEVER seen Dale make a mistake. As far as I can tell, this is simply an extension of that problem, with the gravity taken to zero. So I think we need someone with a kid with a skateboard to do this experimentally. Just have them jump and record the height difference. Then have them push off from a wall on the skateboard and record their speed. Maybe get their friends to do it so we have more data. I would do it myself, but just thinking about a skateboard makes my hip hurt. And simply bending over makes me dizzy these days. [/QUOTE]
