Question
If Superman could throw a baseball very fast and air friction could be ignored, he could put the baseball into orbit. Assume that the balls orbital radius equals 6.38x10^6m. Earth has a mass of 5.98x10^24kg. How fast must Superman throw the ball?

recall that escape velocity
v = √(2GM/d)
v = √(2GM/d)
2gM
