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.
