The height of a soccer ball that is kicked from the ground can
be approximated by the function: y = -16x² + 48x, where y is the height of
the soccer ball in feet x seconds after it is kicked.

returns to the ground.

The time, in seconds, it takes from the moment the soccer ball is kicked until it returns to the ground is 3 seconds

How to determine the time to hit the ground?

The function is given as:

y = -16x^2 + 48x

When the ball hits the ground, we have

y = 0

Substitute the known values in the above equation

-16x^2 + 48x = 0

Factor out -16x

-16x(x - 3) = 0

Divide through by -16x

x - 3 = 0

Add 3 to both sides

x = 3

Hence, the time, in seconds, it takes from the moment the soccer ball is kicked until it returns to the ground is 3 seconds
