Question 76800: Can someone please help me with this question or a similar one Please?
A gun fires a bullet almost straight up from the edge of a 150-foot cliff. If the bullet leaves the gun with a speed of 394 feet per second, its height at time t is given by h(t)=-16t^2+394t+150, 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.)
Thank You,

You can put this solution on YOUR website! A gun fires a bullet almost straight up from the edge of a 150-foot cliff. If the bullet leaves the gun with a speed of 394 feet per second, its height at time t is given by h(t)=-16t^2+394t+150, 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?
:
It's height will be 0 when it lands, right? Therefore h = 0, so we have:
:
-16t^2 + 394t + 150 = 0; solve for t, the positive solution is what we want
:
Use the quadratic formula, a=-16; b=394; c=150

t = +25 seconds, this is only solution we care about.

Make sense to you? I hope it did.
