The largest railway gun ever built was called Gustav and was used briefly in World War II. The gun, mount, and train car had a total mass of 1.22 x 10 kg. The gun fired a projectile that was 80.0 cm in diameter and weighed 7502 kg. In the firing illustrated in the figure, the gun has been elevated at 9- 18.2° above the horizontal. If the railway gun was at rest before firing and moved to the right at a speed v-4.37 m/s immediately after firing, what was the speed of the projectile as it left the barrel (muzzle velocity)? x Units are required for this answer. How far will the projectile travel if air resistance is neglected? Assume that the wheel axles are frictionless. Units are required for this answer. Enter a number with units. Before firing Immediately after firing
