A fireworks show is choreographed to have two shells cross paths at a height of 125 feet and explode at an apex of 159 feet under normal weather conditions. The shells have a launch angle = 70° above the horizontal. If a strong wind induces a constant rightward acceleration of 16 ft/sec² for the fireworks shells, determine the horizontal shift Ax of the crossing point of the shells.

A fireworks show is choreographed to have two shells cross paths at a height of 125 feet and explode at an
apex of 159 feet under normal weather conditions. The shells have a launch angle 0 = 70° above the
horizontal. If a strong wind induces a constant rightward acceleration of 16 ft/sec² for the fireworks shells,
determine the horizontal shift Ax of the crossing point of the shells.
