A fireworks show is choreographed to have two shells cross paths at a height of 146 feet and explode at an apex of 176 feet under normal weather conditions. If the shells have a launch angle = 58° 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.

Multirotor copters (e.g., drones) use multiple fixed propellers to create a downdraft. The momentum of the downdraft must be balanced by the lift force of the drone. Consider plans to fly the same drone to plan a bridge installation in the mountains of Colorado (elevation 7000 ft) to a pipeline installation over the Allegheny mountains in Pennsylvania (elevation 2000 ft). Assuming the drone is capable of flying in each situation and that fair weather exists in each situation, which would differ between the power requirements in these scenarios?
