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?
