Using the formula for initial velocity h=-16t2+VT the height of any object can be found by the time, Annalee serves a volleyball

The ball will hit the ground at 0.125 seconds

<h3>Quadratic function</h3>

The equation of the function is a quadratic function, and the function is given as:

$h = -16t^2 + 2t$

When the ball hits the ground, the value of h is 0.

So, the equation of the function becomes

$-16t^2 + 2t = 0$

Subtract 2t from both sides of the equation

$-16t^2 =- 2t$

Divide both sides by -2t

$8t =1$

Divide both sides by 8

$t =0.125$

Hence, the ball will hit the ground at 0.125 seconds
