der poter factor into the bore the stor. You can enter th text directly Ford, if you came up with a ratio of you could enter the text "sqrt(1/2)" and it will caldate the value for you. Press the Submot battom, then click the blue "Set Factor button in the simulator. Note that the simulation must be stopped to do this. You will know that you've succeeded if you find that the apoapsis of the satellite's orbit now reaches exactly to the green dashed circle. (Also, the simulator will not allow you to proceed until you enter the correct value). Once you have successfully initiated this change in velocity, proceed to the next page of the simulator. OK, we are almost done! The final step is to give the satellite another velocity boost, this time t Point 2. The math is as follows. At Point 2, on the transfer orbit, we have Etr GMm 3R and US- the satellite is on the transfer orbit, its kinetic energy at that point (call it K2,tr) has to be... GMm 2R =
