The small spherical planet called "Glob" has a mass of 6.50×1018 kg and a radius of 5.60×104 m. An astronaut on the surface of Glob throws a rock straight up. The rock reaches a maximum height of 1.64×103 m, above the surface of the planet, before it falls back down. -What was the initial speed of the rock as it left the astronaut's hand? (Glob has no atmosphere, so no energy is lost to air friction. G = 6.67×10-11 Nm2/kg2.)...
