By solving a quadratic equation we will see that the egg will hit the ground after 1.58 seconds.
<h3>How long will take the egg to reach the ground?</h3>
Here we know that the initial height of the egg is 40ft, so the equation for the height will be:
The egg will hit the ground when h(t) = 0, so we need to solve the quadratic equation:
This means that the egg will hit the ground after 1.58 seconds.
