- Homework Statement
- A planet orbits around a star in an ellipse. eccentricity is equal to e, while at the farthest point from the star a meteorite crashes into it, the new velocity of the planet is the same size. But as a result of a meteorite impact, the direction of velocity shifts to an angle θ. which is between 0 degrees and 90 degrees if the eccentricity of the planet's new orbit is e'. Find
a. e' in term of e and θ
b. what angle will the major axis be rotated?(term of e , θ )

I don't know what principle or equation should I start thinking. The one I tried was using the law of conservation, but I found that I didn't know the speed of the meteorite. Anyone have any advice on what principles or equations I should use to get started?
