The distance h traveled in t seconds by an object dropped from a Certain height is h=16t^2. If you dropped an object from 27 feet, how long will it take before it hits the ground?

Answer 1

You are given the equation to represent the distance traveled. Substitute what you know (h=27) then solve for the unknown that remains, t.

27=16t^2 (t is the only unknown)

Solve for t. Solving quadratic equations typically results in a +/- answer but since this is an application to find t, time, you will only use the + answer because we don't use - values for time.
