"MOTION of PROJECTILES in UNIFORM GRAVITY.                      Without air resistance, a projectiles shot off at an angle THETA with respect   to a flat surface has a range RANGE and time of filght TOF that depends on its  initial velocity, V0, gravity G and the angle of elevation THETA.                                     *  *  *                                                   shot at           *             *                                               VELINIT  /     *                   *                                                   /    *                         *                                              /   *___<THETA______________________*_hits surface at time TOF                                                                                             Use these equations when initial velocity and angle of elevation are known.
