    2 gram is hardly a cannonball. It's only buckshot.

    Did you copy that right?

    Velocity from falling has nothing to do with mass. It's only gravity, and height.

    Velocity = sqrt. (2gh), = sqrt. (19.6 x .01), = 0.4427m/sec.

    GPE = (mgh), = .002 x 9.8 x .01, = .000196j.

    Where did .000194 come from?
