Question
A spacecraft starts in elliptical orbit JK (red solid curve) around some planet and transfers to elliptical orbit MN (blue solid curve). To do so, it changes its speed at Kand inserts into the circular orbit KL (dashed green curve). At L, it changes speed again to insert into elliptical orbit LM (dashed magenta curve). Finally, at M, it changes speed to insert into the final orbit MN. Find all the changes in speed. Mass of planet compared to mass of Earth: Mplanet /MEarth = 0.75 Radius of planet: Rplanet = 3000 mi a = 400 mi b = 1200 mi c = 300 mi d = 1000 mi
I just want to make sure I did it correctly before submitting my answer (ATTACHED)
