A fireworks show is choreographed to have two shells cross paths at a height of 160 feet and explode at an apex of 192 feet under
normal weather conditions. If the shells have a launch angle 0- 70° above the horizontal, determine the common launch speed vo for
the shells, the separation distance d between the launch points A and B, and the timet from launch at which the shells explode.
