In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy. The Earths escape velocity is about 11.2 kilometers per...
I believe orbital velocity is about 73% of escape velocity at the same distance from the mass center of the body being orbited. Could be 71% because escape velocity divided by the square root of 2...
I think I found it on Wiki. Looks like Phobos' e/v is about 25 mph, & deimos' is 12.5 mph. Idk if one can jump up that fast in a space suit, but it's close.
