The height h, in feet, of objects such as thrown balls can be modeled as a function of time
t, in seconds, as h(t) = -16t? + v0t + h0, where the initial upward velocity is v0, in feet
per second, and the initial height is h0, in feet.
marla and kerry are practicing lacrosse tosses. marla throws a ball from a height of 6
