Drag force at Bolivia: 4.67 N
Drag force at Sea level: 6.73 N
Side_force at Bolivia: 3.03 N
Side force at Sea level: 4.37 N
From this results it is possible to say that the percentile change in the forces at Bolivia when compared to the Sea level forces is of 30.6% less.
The percentile change is the same as the percentile change for the density at this two different locations, so we can see the relation with this parameter.
At higher altitudes the ball will have less drag forces as well as less side forces acting on it, when compared to sea level conditions.
