Using the formula for initial velocity h=-16t2+VT the height of any object can be found by the time, Annalee serves a volleyball with a initial velocity of 30 feet per second, how long will it take to hit the ground

Sagot :

The ball will hit the ground at 0.125 seconds

Quadratic function

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

[tex]h = -16t^2 + 2t[/tex]

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

So, the equation of the function becomes

[tex]-16t^2 + 2t = 0[/tex]

Subtract 2t from both sides of the equation

[tex]-16t^2 =- 2t[/tex]

Divide both sides by -2t

[tex]8t =1[/tex]

Divide both sides by 8

[tex]t =0.125[/tex]

Hence, the ball will hit the ground at 0.125 seconds
