Then I'm just not sure of what its speed far away from Earth would be.

Would it be v = sqrt(G*M(earth)/R) where R is the distance between the center of the Earth and the object?

Homework Statement (a) What is the escape speed from the sun for an object in the Earth's orbit (of orbital radius R) but far from the Earth? (b) If an object already has a speed equal to the Earth's orbital speed, what additional speed must it be given to escape as in (a)? (c) Suppose an...
