Jimmy and his friends went for a walk throughout downtown Holland.

They saw these cool looking water balloons in a store window, they decided to buy a pack.

Jimmy and his friends saw a stair case leading up a tall building, they decided to climb it.

Once they reached the top, Jimmy had an idea...

"Lets throw water balloons off the building! But we need to know how long it takes to hit the ground so it doesn't hit anyone."

Jimmy and his friends are 288 feet above ground level. They need to figure out how long it takes to hit the ground by using this function... "-16t^2+288"

His friends remember their teacher talking about it during class. They start to explain the process to Jimmy.

-16t^2+288=0
