Considering the given quadratic function, it is found that it will take 4.05 seconds for the frog to land on the ground.
<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:
The solutions are:
In which:
The height after t seconds is given by:
h(t) = -16t² + 64t + 3.
it hits the ground when h(t) = 0, hence:
-16t² + 64t + 3 = 0
16t² - 64t - 3 = 0.
The coefficients are a = 16, b = -64, c = -3, hence:
Time has to be positive, hence the frog lands on the ground after 4.05 seconds.
