I have a question that is not present in any physics book I've ever seen: Supose I have a rocket with infinite fuel, but it's mass is constant. This rocket's power is limited and can only provide enugh thrust to accelerate it self at a rate of just over 9.81M/s. If I were to lunch this rocket straight up into the air with a equipment onboard(with zero mass) that will absolutly keep the rocket from changing direction. The question is, is this rocket able to get into space (higher than the lowest stable earth orbit). The second question is, without increasing it's power, is it possible to enter an earth orbit after it's in space. --- this question is driving me crazy trying to convince people that the escape velocity and so on don't apply to this situation..... They just keep saying I make no sense and nothing can go into space without a minimum orbit velocity.
