gives the position s in feet above the ground, where t is the number of seconds elapsed after a ball is projected upward from a building. Determine the height of the building, if possible. Explain your reasoning.
What will be an ideal response?
The height of the building is 520 ft. It is determined by letting t = 0 and solving for s.
