Homework Help: Galileo's Theory of falling bodies problem

  1. Jul 15, 2009 #1
    1. The problem statement, all variables and given/known data
    If an object falls five meters during the first interval of time, what is the total distance fallen at the end of the second interval of time? (Galileo's Theory of falling bodies)

    2. Relevant equations

    3. The attempt at a solution
    I know that at successive intervals of time the distance fallen is proportional to the odd numbers. So I suspect it to be 12, but apparently I'm wrong.

    Use you kinematic equations to help you out here.

    Re: Acceleration

    That's right. Another way to say that is
    • The object falls a distance 1x in the 1st time interval.
    • The object falls a distance 3x in the 2nd time interval.
    • Then 5x in the 3rd time interval, etc. etc.
    So the question is, what is x, given what they tell you about the 1st time interval?

    Yes, that's wrong. Again, what is the value of x here?
