This is an estimate, making it as unfavorable as possible (favorable = showing a fake). Taken to be a 'cannonball', sphere of radius 56 cm. Drag coefficient taken to be 0.5 (it is in 0.5 to 1.5 range and depends on velocity. Turns out to be sensitive to method, so velocity first, coordinates later (least favorable result this way). Initial speed is taken to be sound speed. Trajectory shown.
