A tractor pulls a log 800 meters up a hill with a grade of 4%. The force on the cable connecting the tractor and the log is 1600 kg at a 35° angle with the road. To the nearest tenth, approximate the work completed.

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
