A fireworks show is choreographed to have two shells cross paths at a height of 168 feet and explode at an apex of 213 feet under normal weather conditions. If the shells have a launch angle 0 = 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. 45' 168' Answers: Vo = ft/sec d = ft t = sec A fireworks show is choreographed to have two shells cross paths at a height of 168 feet and explode at an apex of 213 feet under normal weather conditions.
