Suppose that several projectiles are fired upward. Which one will be in the air longest? (R is range, h is highest elevation, and t is time of flight.)
A) The one with the highest maximum elevation, h
B) The one with the greatest initial velocity
C) The one with the minimum elevation, h
D) The one with the farthest range, R
E) The one for which the product of (R)(t)(h) is maximum

Quizplus · Accepted Answer

The time a projectile is in the air is most directly influenced by its maximum elevation, h. The higher the projectile goes, the longer it will stay in the air due to the longer ascent and descent times, regardless of its range or initial velocity.
