(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Early in the space program a jet aircraft was used to simulate "weightless" space flight. Beginning from a comfortable cruising altitude, assume such a craft could reach a speed of v = 590 m/s at an angle q = 30.9° above the horizontal. Subsequently the engines were used only to overcome air friction, and the plane followed a "free fall" path.

How long could "weightlessness" experiments be done before the plane fell back to its original altitude?

2. Relevant equations

I do not understand what the problem is asking me. I understand what free fall is and how it relates to orbit and "weighlessness" but I 'm not getting what they are asking.

I mean how does the angle play into orbit, if I dont know the original alititude??

Please someone help, --i just need question reasked in a different way ??

thanks for any help!
