Re: [Phys-l] truck mileage

Kathy,
 
I might add that these factors hold in Murfreesboro, and are all
compounded on that horrible stretch called "White Mountain" on the way
to Shelbyville.

I have quite an interesting problem that I cannot explain...

Our Ag teacher set up this scenario for me:

one 5000# truck gets about 18 miles per gallon
same 5000# truck pulling a 4000# trailer gets 8 miles per gallon
same 5000# truck pulling a 4000# trailer + 10000# of cows ALSO  gets 8 

miles per gallon.

Any ideas why the empty and the full trailer both get the same  
mileage?  This same pattern is also present in a different trailer and 

truck combination.

thanks,
Kathy
