A projectile is shot directly away from Earth's surface. Neglectthe rotation of the Earth. What multiple of Earth's radius RE givesthe radial distance (from the Earth's center) the projectilereaches if (a) its initial speed is 0.440 of the escape speed fromEarth and (b) its initial kinetic energy is 0.440 of the kineticenergy required to escape Earth? (Give your answers as unitlessnumbers.) (c) What is the least initial mechanical energy requiredat launch if the projectile is to escape Earth?
