1. The problem statement, all variables and given/known data A planet has an eccentricity of 0.006800 and a semimajor axis of 0.7233 AU, find the ratio of ortibal speed at perihelion to that at aphelion. 2. Relevant equations d=e x a L=mvrsin[tex]\theta[/tex] 3. The attempt at a solution I plugged in and solved for the distance between the foci (0.004918) and then set the angular momentum constants equal to each other: m v(p) rmin sin[tex]\theta[/tex]=m v(a) rmax sin[tex]\theta[/tex] the masses and sin[tex]\theta[/tex] cancel out, so v(p) x r min = v(a) x r max and so the ratio is: v(p) / v(a) = r max / r min r max is the semimajor axis, and r min is the semimajor axis minus the d as found above: So, it should be .7233/.718382 which gives me 1.00685, but this was incorrect according to my online homework, could you tell me what I did wrong?
