A fireworks show is choreographed to have two shells cross paths at a height of 107 feet and explode at an apex of 141 feet under normal weather conditions. If the shells have a launch angle e - 55° 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 time t from launch at which the shells explode.
