11-80.

A golf ball is hit at an angle of

## Projectile MotionAn object that is launched with an initial position of will travel along a path defined by the parametric function: where are measured in feet and is measured in seconds. |

First determine how long the ball was in the air, that is, when does the ball hit the ground or have a height of

This is done by solving .

Once this time is known, it can be used to calculate the horizontal distance traveled.
