Putting an item into orbit. Help

[Squeek]

Homework Statement

No idea how to do this honestly, but here it is. Hopefully someone can just work this out and I can learn from that. Calculate the velocity needed to place a 14.5kg item (its a turkey but whatever lol) into orbit around the Earth at an elevation of 100km. The radius of the Earth is 6500km. Like I said I'm not sure to how to do this and I need to know.

Homework Equations

I was given formulas ( These might have nothing to do with it, beware) Fc=mu²/r
ac=4pi²rf²

The point is I don't know how to do it, I have no work. Obviously I'm not going to get any help so someone just delete this...

In general you know that there will need to be a conservation of energy to accomplish this don't you?

So doesn't the sum of the PE at surface + KE initial = PE at orbit + KE of object in orbit?
