The citizens of Paris were terrified during World War I when they were suddenly bombarded with shells fired from a long-range gun known as Big Bertha. The barrel of the gun was 36.6 m long and it had a muzzle speed of 1.46 km/s. When the gun's angle of elevation was set to 55°, what would be the range? (The actual range at this elevation was 121 km; air resistance cannot be neglected for the high muzzle speed of the shells.)

i think you need to include drag
that is the air resistance
it is proprtional to the velocity of the object 
it is given by the formula
Fd=Bv
where B is a constant and v is the velocity of the object
so i think we need to know the constant B for the air

thanks for the help but i already found out how to do this ^_^
i don't need include any kind of friction 
just solve like the other common problems, and they just put the length of the barrel 36.6m, to confuse students like me XD

thanks for taking the time, appreciate it ;p
