The height h in feet of an object t seconds after it is dropped can be modeled by the quadratic equation h=-16t^2+h0, where h0 is the initial height of the object. Solve the equation h=-16t^2+255 for t, using the quadratic formula to determine the time it takes the rock to reach the canyon floor.

The rock will take approximately 3.992 seconds to reach the canyon floor.

Step-by-step explanation:

For all , its roots are determined by the Quadratic Formula:

In this case, it corresponds to instants when rock is either launched or hits the floor. If we know that , and , the time it takes the rock to reach the canyon floor is:

The rock will take approximately 3.992 seconds to reach the canyon floor.

ian gonna lie that is way to much
