    I don't know how to start with this question:
    Demonstrate that the following equation is homogeneous with respect to units. The symbols have their usual meanings.
    x = u t + 1/2(a t^2)

    x is measured in meters
    u is measured in meters per second
    t is measured in seconds
    a is measured in meters per second squared
    1/2 is dimensionless (no units)

    Run through the units and make sure that you have the same thing on both sides when you multiply through.
