'cause I've been ruminating about it.... So let's take this from the base model-- Base model ignores the following-- Rotation AIr Resistance you have the earth and a hole from where you are, going straight thru the center and right out to the other (...)

(...) Sounds right to me. Acceleration adds linearly, so when you integrate to get the velocity, you have the integral of the thrust plus the integral of the gravitational acceleration. Assuming that the change in mass of the rocket due to depleted (...) (19 years ago, 8-Jun-05, to lugnet.off-topic.geek)
