Oooo...

This one looks pretty fun. May even have potential applicable for an old idea i had to make real life pod racers that'd travel primarily over water (for sheer safety).

Basically what I'm gonna to do is take the formula for escpape velocity, isolate the force of gravity, subtract (well, negative addition) the force from surface tension. Basically, the escape velocity, if you achieve it at surface level in a horizontal direction, you'll continue along the vector you're travelling (ie, horizontal.). He'll not reaching that effect on his own, the force upward from surface tension is providing the remainder., ST=F/l. I'm wondering what value l to sub in. Have put the question to my Society, should have the compounded answer by then.

sqrt(GM/r) G=Grav constant. M= planet mass, r=radius of planet.

Fgrav=GMm/r^2 let's see:

v2=GM/r

v2/r=Fgrav.

v2/r=sigmaF=Fgrav-Fst

Fgrav=9.81*130=1275.3 N. r=6 378 000 m ST=71.92, Surface area of foot, say 0.02 m^2 depth of foot say 0.04 m.

Will get back to this as soon as I get confirmation on how to get the last part...
