I was thinking that as well but i would be interested to know what the FPS differential would be if paintball was played on another planet.
Earth = 300 FPS MARS = ??? FPS

if you jump up you never land on the same spot again (atom for atom)
point a cannon at 90 degrees to the ground .... and when it fires jump down the barrel
any money it wont come down and hit you in the head... and if it does i wont have to pay you anyhoo

Good find, but a question to you all......
Why are all Planets round ?
tiny prize for the first correct reply..

Your outcome is correct but its not exactly to do with a difference in momentum.
Air resistance and mechanical friction are slowing the person and the truck down, but the trucks engine keeps them going at 40.
The jumper is outside the truck (on the flatbed trailer) so he will experience alot of air resistance just like the truck.
So long as he holds on to the truck, he will get enough propulsion from the truck (which is driving at 40mph), to maintain 40mph.
Once the person jumps, he is no longer being pulled forwards by the truck, but he still has the same amount of air resistance trying to slow him down.
The truck has its own means of propulsion so keeps driving happily at 40 as the jumper decelerates. Its momentum is irrelevent because its not changing speed.
Even if it did lose propulsion, theres no reason to say the truck would decelerate less than the person.
Of course the truck has much more inertia 'trying' to maintain its speed, but it also has alot more air resistance, and mechanical friction slowing it down, where as the man just has air resistance.
Also it depends where he stands on the truck how much air resistance he feels.
And In any case, we shouldnt be driving flatbed trucks...
By the looks of the first picture, it wont be long before our nasty carbon footprints start affecting the climate on Antares.
Think of the poor little Antares creatures... im welling up..
I thought they were technically, elliptical or semi Burger shaped actually...
Russell.. is it because God was having fun with a bouncy ball while talking to his other friends who were creating the other planets and they all wanted a go but couldn't so the shaped their planets like the bouncy ball, and God followed on from this?
