| Subject: [Phys-l] truck mileage
|
| >
| 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
