A fi reworks show is choreographed to have two shells cross paths at a height of 160
Question:
A fi reworks 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 θ = 60° above the horizontal, determine the common launch speed v0 for the shells, the separation distance d between the launch points A and B, and the time from launch at which the shells explode.
