The S is height and t is seconds.
This is a word problem and I have no clue how to solve it.
Mt. Thor in Canada is said to have the longest vertical drop(4100 ft.) on Earth. How long would it take for a pebble dropped off the cliff to reach the ground? (Hint: The height of a falling object above the ground t seconds after it is dropped can be modeled by s(t) = -16t^2 + So where So is the initial height.)
thanks Dan. I have no clue where to go from here. When I entered it in my calculator I came up with S(16)=4 S= 16 secs. with 4 being the So? I have to find out how many seconds it would take for the pebble to be dropped from 4100 ft to hit the ground. I have never done a problem like this nor do I know how to figure it out.
