Answer:
The rock will reach to the canyon floor in 3.99 seconds.
Step-by-step explanation:
The height h (in feet) of an object t seconds after it is dropped can be modeled by the quadratic equation

Where, h0 is the initial height of the object.
It can be written as

The height of the object is zero if it will reach to the canyon floor.

Quadratic formula:

Here a=-16, b=0 and c=255.



Time cannot be negative, therefore the rock will reach to the canyon floor in 3.99 seconds.
