(a) Show that if a projectile is launched straight upward from the surface of the earth with initial velocity vo less than escape velocity 2GM/R, then the maximum dis- tance from the center of the earth attained by the projectile is 2GMR Imax 2GM – Rvž where M and R are the mass and radius of the earth, re- spectively. (b) With what initial velocity vo must such a projectile be launched to yield a maximum altitude of 100 kilometers above the surface of the earth? (c) Find the maximum distance from the center of the earth, expressed in terms of earth radii, attained by a projectile launched from the surface of the earth with 90% of escape velocity.
