A fireworks show is choreographed to have two shells cross paths at a height of 167 feet and explode at an apex of 204 feet under normal weather conditions. If the shells have a launch angle e- 63° 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. 37' 167' A/0 Answers: Vo- ft/sec d = i ft t = sec

A fireworks show is choreographed to have two shells cross paths at a height of 167 feet and explode at an apex of 204 feet under
normal weather conditions. If the shells have a launch angle 0 = 63° 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.
