If there were no air resistance, a quarter dropped from the top of New York's empire state building would reach the ground 9.6 seconds later, what would its speed be? How high is the building?

  • Physical Science -

    distance = 1/2*g*t^2

    velocity = g*t

  • Physical Science -

    I don't know how to use those formulas to figure out what the speed and how high the building would be ?

  • Physical Science -

    distance = 1/2*g*t^2
    distance is what you want.
    1/2 is obvious.
    g = 9.8 meters/secnd/second
    t = time = 9.6 seconds in the problem. Solve for d.

    Okay, thank you! I'm pretty sure I got it! What about to know how high the building is though? Sorry if you already answered that too, I am awful with this kind of stuff

  • Physical Science -

    The distance IS how high.
