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 1.48 km/s. When the gun's angle of elevation was set to 50°, 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.)
