An astronaut, whose mission is to go where no one has gone before, lands on a spherical planet in a distant galaxy. As she stands on the surface of the planet, she releases a small rock from rest and finds that it takes the rock 0.580 ss to fall 1.90 mm.     Part A If the radius of the planet is 9.50×107m9.50×107m, what is the mass of the planet? Express your answer with the appropriate units.
