Answer
The baseball coach can determine which player among his team can throw the ball the farthest in the least time.
Work Step by Step
We know that the parametric equations of a projectile give the horizontal as well as the vertical position of the point. Therefore, it is easy to determine the maximum height, the maximum horizontal distance and the time of flight of the projectile from these equations. Hence, a baseball coach can study these values for all of his players and determine his pitcher accordingly.
