    1. The problem statement, all variables and given/known data

    A stick of length 0.8 m is held vertically with one end on the floor and is then allowed to fall. Find the speed of the other end when it hits the floor, assuming that the end on the floor does not slip.

    2. Relevant equations


    Should I use I=.5ML^2 or I=1/3ML^2

    3. The attempt at a solution

    Used the relevant equation to no success.

    The moment of inertia of a rod from one of its ends is 1/3 M L^2, which you can find in a table.
