Question 1087296: An object is 2,722 ft high. How long will it take it
falling freely, to reach the ground? Use the formula s = 16t2
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
Assuming there isn't any wind resistance, the answer is about 13.043197 seconds
See below on how I got that value.
-------------------------------------------------------------------------
Replace 's' with the given height. The goal is to solve for t
Divide both sides by 16
Apply the square root to both sides
Keep in mind that negative t values make no sense, so
Use a calculator to compute the square root
I'm deciding to round to 6 decimal places. You can round to whatever you want depending on your teacher's preference.
Side Note: this is assuming that there is no wind or air resistance. The object would have to be in a vacuum for this solution to make sense. Of course, such a scenario is very unlikely. The teacher is opting to ignore air resistance because that topic involves much more complicated math.
