    Assume a man steps off the cliff of 500 m. How long will it take him to fall 500m.

    Think of the acceleration due to gravity, which is constant, 9.81 m/s2.

    How long does it take an object to travel 500 m with an constant acceleration of 9.81 m/s2? This is a pretty basic problem.

    My guess would just be that he just didn't know the acceleration due to gravity.

    But yes, I couldn't have explained it better then Astronuc. :) Need anymore help with studying for the test?
    Good luck with it, by the way.
