A physics class is using simulation software to study water bottle rockets before attempting to build one for the National Physics Competition. Their first simulation is of a rocket without a parachute launched from the roof of the gymnasium. The scatterplot shows the approximate path of the rocket. The software program generates the equation h = –4.9t2 + 39.2t + 14 to model the data, where h is the height in meters of the rocket t seconds after it was launched. What does the number 14 most likely represent in this equation?
A. The number of seconds the rocket was in the air
B. The height of the gymnasium from which the rocket was launched
C. The number of seconds that it took the rocket to reach its maximum height
D. The maximum height of the rocket
Answer:B
