Liz, it's not 2.3, but 2.46 km/s.
I agree about the masses :) It's given in the problem and equals 2100 (you have twice as much for some reason). We get the square root of 2*2100*110. Either I'm really messing up, or something else is wrong :) But I get 680 m/s. It doesn't match the answers at all.:smile04:

To resolve the problem, I suggest conducting an experiment and checking in practice what speed is needed for this.

O God of Earth and Altar,
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
