    The givens are as follows:

    initial velocity (vi) = 6 m/sec

    acceleration = - 9.8 m/sec^2 (the negative sign refers to the direction)

    final velocity (v) = 1.1 m/sec

    initial position (xi) = 0 meters

    Now, we will use the equations of motion to get the displacement as follows:

    v = vi + at

    1.1 = 6 - 9.8t

    9.8t = 6-1.1 = 4.9

    t = 0.5 sec

    x = xi + vit + 0.5at^t

    x = 0 + (6) (0.5) + 0.5 (-9.8) (0.5) ^2

    x = 1.775 meters
