Gabe drops a hammer from an apartment that is 30 meters above the ground. the height of the hammer in meters, h, after t seconds is modeled by the function below h(t)=-t^2-t 30 find the number of seconds it will take for the hammer to hit the ground

The hammer will hit the ground after 5 seconds.

Step-by-step explanation:

The height of hammer is defined by the function

Where, t is time in seconds.

The value of h(t) is 0, when hammer will hit the ground.

Equate each factor equal to 0.

The time can not be negative, therefore hammer will hit the ground after 5 seconds.
