An object drops a distance h in a time of 6.3 s on the surface of the earth (neglecting air effects) .How long would it take the same object to drop the same distance on the surface of spherical asteroid X having a mass of 1.1 × 1022 kg and a radius of 4.0 × 105 m? (G = 6.67 × 10-11 N ∙ m2/kg2,Mearth = 5.97 × 1024 kg,Rearth = 6.38 × 106 m)
