During World War I, the Germans had a gun
called Big Bertha that was used to shell Paris.
The shell had an initial speed of 1.66 km/s at
an initial inclination of 38.8 to the horizontal.
The acceleration of gravity is 9.8 m/s^2
How far away did the shell hit? (in km)
How long was it in the air (in s)
