Aprojectile is launched from the surface of a planet (mass = 15 x 1024 kg, radius = r = 9.6 x 106 m). what minimum launch speed is required if the projectile is to rise to a height of 6r above the surface of the planet? disregard any dissipative effects of the atmosphere. put your answer in km/s.

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
