A fireworks show is choreographed to have two shells cross paths at a height of 134 feet and explode at an apex of 179 feet under normal weather conditions. If the shells have a launch angle 0 = 67° 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. 45' 134' A/e e B d- Answers: Vo= i ft/sec d = i ft t= i sec
