# POLQ 3 | Lesson 4 | Practice (Quadratic Word Problems)

1).  Batter Up – A baseball is launched by a batter upwards from a height of 4 feet with an initial velocity of 160 feet per second.

The formula for vertical motion of an object is $$h(t) = 0.5at^2 + vt + s$$, where the gravitational constant, $$a$$, is –32 feet per square second, $$v$$ is the initial velocity, and $$s$$ is the initial height. Time, $$t$$, is measured in seconds, and height, $$h$$, is measured in feet.

What function describes the height, $$h$$, of the baseball $$t$$ seconds into launch?
