An object drops a distance h in a time of 6.3s on the surface of the earth (neglecting air effects). How long would it take the sam object to drop the same distance on the surface of sperical asteroid X having a mass of 1.1 x 10^22 kg and a radius of 4.0 x 10^5m? (G =6.67 x 10^-11 N x m^2/kg^2, Mearth=5.97 x 10^24 kg, Rearth=6.38 x 10^6m)
A) 3.3 s B) 9.2 s C) 12 s D) 5.2 s E) 6.3 s
