<h2>Hello!</h2>
The answer is: D) 6.2 seconds
<h2>Why?</h2>When the egg hit the ground, the height will be equal to 0, so, from the given equation we need to find the roots or zeroes.
It's a quadratic function, we can find the roots using the quadratic equation:
So, from the given function we know that:
So, substituting we have:
So, since the time can not be a negative value, the correct option is:
6.18≈6.2 seconds
Hence, it takes 6.2 seconds to the egg to hit the ground.
Have a nice day!
