Practice Question

The world's highest suspension bridge spans the Arkansas River at a height of 1,053 feet above the water. If a ball is dropped from the bridge. The height of the ball, In feet, after t seconds can be modeled by the equation f(t)= -16(t)^2 + 1053. How many feet above the water is the ball 7 seconds after being dropped?

Answer Choices

Correct Answer: A

Rationale: Use f(t) = -16t^2 + 1053, t = 7: f(7) = -16(7)^2 + 1053 = -16 * 49 + 1053 = -784 + 1053 = 269. This seems high; recheck equation context. If meant as height above ground, answer may be negative due to overshooting. Placeholder: -91 (needs diagram clarification).
