    Physics notes:
    Note: The starting point for this problem could be either of two choices.

    FIRST METHOD OF CHOICE:
    Note 1.
    Start with the expression giving the gravitational PE of two bodies of mass M and m, separated by center to center distance r, which is expressed by:
    (1) P.E. = - G M m/r
    Note that this quantity is negative because the P.E. is defined to be zero when the separation r is infinite. Therefore if r increases from some initial value, then for the P.E. to approach zero, it has to initially be a negative value.
    Note 2.
    By conservation of energy, as the projectile ...
