Your auto, parked in the drive, sits atop a scale, the scale reads 2800 lbs.  
Now you are driveing the highway at say, 70 miles per hour, and pass atop 
another scale, the same lenght and width as your auto.  Will this second scale 
read 2800 lbs, or will it be less?   If the same, why do racecars sport a rear 
spoiler?                                     Thanx,  Nick
