A ladder 25 feet long is leaning against the wall of a building. Initially, the foot of the ladder is 7 feet from the wall. The foot of the ladder begins to slide at a rate of 2 ft/sec, causing the top of the ladder to slide down the wall. The location of the foot of the ladder at time t seconds is given by the parametric equations (7+2t,0).

![### Sliding Ladder Problem
A ladder 25 feet long is leaning against the wall of a building. Initially, the foot of the ladder is 7 feet from the wall. The foot of the ladder begins to slide at a rate of 2 ft/sec, causing the top of the ladder to slide down the wall. The location of the foot of the ladder at time \( t \) seconds is given by the parametric equations \((7 + 2t, 0)\).
#### Diagram Explanation
The diagram shows:
- A vertical wall labeled "wall".
- A horizontal line representing the ground, labeled "ground".
- A ladder leaning against the wall, forming a right triangle with the wall and the ground.
- The ladder is 25 feet long.
- An arrow indicates the foot of the ladder is initially 7 feet from the wall.
- There is a downward arrow along the wall indicating the sliding motion of the top of the ladder down the wall.
#### Problem Statement
(a) The location of the top of the ladder will be given by parametric equations \((0, y(t))\). The formula for \( y(t) \) is:
\[ y(t) = \underline{\hspace{5cm}} \]
