Escape speed from earth and its initial kinetic energy

Reference no: EM13536601

A projectile is shot directly away from Earth's surface. Neglect the rotation of the Earth. What multiple of Earth's radius RE gives the radial distance (from the Earth's center) the projectile reaches if (a) its initial speed is 0.550 of the escape speed from Earth and (b) its initial kinetic energy is 0.550 of the kinetic energy required to escape Earth? (Give your answers as unitless numbers.)
