<p>venus has a rotational period of 243 days. what would be the altitude of a geosynchrous satellite for this planet?</p>
<p>i think you have to use kepler third law. </p>
<p>(Ta/Tb)^2=(Ra/Rb)^3
i’m not sure if it is up till the third power for the right side. it might be ^3=^2</p>
<p>T^2 = k*(r^3)</p>
<p>but how to find k?</p>
<p>oh come one guys… i need this problem done by tomorrow.
no one has any idea?</p>
<p>i was thinking that you could assume that the sun revolved around venus with a period of 243 days… but i cant get the math to work.</p>
<p>there must be an easier way/something im missing</p>
<p>i think you can assume that a satellite is a planet. (Ta / Tb)^2 = (Ra / Rb)^3
also if you solve it this way you don’t need the value of k. do you have the value of the radius of venus? if you don’t i don’t think it is possible.</p>
