Question on delta-v and escape velocity?

shizz · 2012-02-18 16:31:58

If I was to calculate the escape velocity of a body, e.g. the earth which is approx. 11.2km/s, could this then be used as the delta-v in the ideal rocket equation to calculate the mass ratio needed? This would be for both a trip to the moon and to Mars so it's not just LEO. That's why I presume the escape velocity is the…

This would be for both a trip to the moon and to Mars so it's not just LEO. That's why I presume the escape velocity is the delta-v in this case?
