Question

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 0.444 of the escape speed from Earth and (b) its initial kinetic energy is 0.444 of the kinetic energy required to escape Earth? (Give your answers as unitless numbers.) (c) What is the least initial mechanical energy required at launch if the projectile is to escape Earth?

Explanation / Answer

This is a case of problems related to gravitation.

in case a) it is required the projectile reaches the radial distance form the Earth center. That is to say that the projectile must reach two Earth
