A missile is fired from the ground with an initial velocity v0 forming an angle ? 0 with the vertical. If the missile is to reach a maximum altitude equal to ? R, where R is the radius of the earth,(a) Show that the required angle ? 0 is defined by the relation where is the escape velocity,(b) Determine the range of allowable values of v0.
