A projectile is shot directly away from Earth's surface. Neglectthe rotation of Earth.
(a) As a multiple of Earth's radius RE, what is the radial distancea projectile reaches if its initial speed is one-half of the escapespeed from Earth?
(b) As a multiple of Earth's radius RE, what is the radial distancea projectile reaches if its initial kinetic energy is one-tenth ofthe kinetic energy required to escape Earth?
(c) What is the least initial mechanical energy required at launchif the projectile is to escape Earth?
