    how can negative angular velocity (back spin) be calculated when the ball is struck by a lofted club?

    Can't help, man. The only thing that I know about the angular velocity of a golf ball is that no matter how I hit it, it will always travel at least 35º tangental to the direction in which the hole lies.

    Sketch it: draw the impact and launch angles, assuming angle of impact equals (equal and opposite) the launch angle. Since the impact point is not parallel to either the impact or launch directions, a triangle is formed, with one side being the initial linear speed, one being the final linear speed and the third being the tangential (rotational) speed.

    I've actually never tried, so I'm not certain of this, but it should work...
