Final answer:
The question requires solving a problem related to projectile motion within the historical context of World War I artillery, specifically referencing 'Big Bertha'. It involves calculating the range of the gun using the initial muzzle velocity and angle of elevation, assuming no air resistance.
Step-by-step explanation:
The question deals with the scenario of a cannon fire during war, specifically during World War I, involving the assessment of projectile motion without air resistance. The historical context introduces the 'Big Bertha,' a notable artillery piece. For the physics problem, assuming no air resistance, the projectile motion can be solved by breaking the velocity into horizontal and vertical components and then using kinematic equations.
Big Bertha's range when fired at an elevation of 55.0° with a muzzle speed of 2.20 km/s can be calculated using the formula for projectile motion: Range = (v^2 × sin(2 × angle)) / g, where v is the muzzle velocity, angle is the angle of elevation, and g is the acceleration due to gravity.
In general, projectile motion problems require understanding of the following concepts:
Initial velocity
Maximum height
Range of the projectile
Earth's curvature effect on projectile motion
