The question is(adsbygoogle = window.adsbygoogle || []).push({});

If after Halley's comet hits the earth, the earth continues to move in its initial direction but with a greater speed (1.12 times) , find the new semi-major and semi-minor ases of the new earth orbit in terms of the original R.

So, my question is, do you think that the angular momentum of the earth is conserved in this process? or is R conserved in the process( which means R does not change)?

The question assumes that the earth is initially moving in the circular orbit, then after the collision it moves in a elliptical orbit.

Thanks for any help!
