Rocket Science, Revisited

In a previous post, I suggested that it is better to run into a rocket than to run away from it. Recently, a friend pointed out a small oversight on the reasoning.

The oversight is relative velocity. Evidently, running into a rocket means that the rocket will hit you at a higher velocity as compared to when you are running away from the rocket. However, the original considerations on the rocket's acceleration are still valid.

The optimal solution seems to be to run towards the rocket, then to jump back with all your might an instant before the rocket hits you.
