Homework Help: Problems with minimal information

  1. Sep 23, 2012 #1
    An object dropped from the top of a cliff takes 1.80 s to hit the water below. What is the height of the cliff?

    I do not know of any equation that would work as only one piece of information has been given

    I could not even begin my calculations as I lacked information. Is it possible to solve this question?

    You know the time, you know the acceleration (free fall), you know the initial velocity ("dropped" means vo=0). You can find the distance traveled.
