Escape Velocity

If the kinetic energy of an object launched from the Earth were equal in magnitude to the potential energy, then in the absence of friction resistance it could escape from the Earth.
Escape velocity from the Earth
If M = MEarth

and r = rEarth

then vescape = m/s

vescape =km/hr
vescape =mi/hr
