A gun fires a bullet almost straight up from the edge of a 140-foot cliff. If the bullet leaves the gun with a speed of 556 feet per second, its height at time t is given by h(t)=−16t2+556t+140, measured from the ground below the cliff.

When will the bullet land on the ground below the cliff? (Hint: What is its height when it lands? Remember that we are measuring from the ground below, not from the cliff.)

The bullet will land after seconds.

thank you!
