1. The problem statement, all variables and given/known data A meteoroid with a velocity (when the effect of the Earth's gravity has been eliminiated) of 49.9 km/s when it is at a distance of 1.50x10^11m from the sun. (a) Using energy calculations show that this object has an open orbit and is therefore not restricted to our solar system (b) Calculate what the velocity of this meteoroid would be when it was infinitely far away from the sun 2. Relevant equations v = sqrt (2GM/r) 3. The attempt at a solution For (a) I just plugged in v = 49 900 m/s G = constant r = 1.50x10^11m And I solved for M which was 9.33x10^30 kg which doesn't equal the earth of the mass so that shows that it isn't part of our solar system. Then for (b) I used the same equation I used above and plugged in r = infinity which eventually leads to 0. So does the v eventually go to v = 0 m/s?
