A fireworks show is choreographed to have two shells cross paths at a height of 160 feet and explode at an apex of 200 feet under normal weather conditions. If the shells have a launch angle 0 = 60° above the horizontal, determine the common launch speed vo for the shells, the separation distance d between the launch pointsA and B, and the time t from launch at which the shells explode. 40' 160' A/0 e B
