A fireworks show is choreographed to have two shells cross paths at a height of 104 feet and explode at an apex of 151 feet under normal weather conditions. If the shells have a launch angle θ = 54° 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 t from launch at which the shells explode.   Determine the common launch speed v0 for the shells.

Types of scheduling techniques

We need to use project scheduling techniques or planning strategies in a project to align all its features so that it works seamlessly. The plan must be within the scope of the project and all its resources must be used efficiently. Given the flexibility of the project and its scope, it is difficult to plan it, but we are expected to do it because we are the ones who will be held accountable.
