41cm Guns fires an 2200lb shell at 2,600 ft/s, what is Nagato's maximum cruising speed for her to not run into her own shell during her special attack?

Since size is around for the gun is 18m, and guns look about ~1m long, we can infer the shell is about 1 inch, size of a big bullet.

To clear her body and the turret on the other side, the shell need to travel about 120 times its length. The time which divided by the 2600 ft/s is around 4ms to clear.

lets say she fires at an 10% angle and gives a clearance of 2 inches. At 60mph, she will run into the bullet at ~2ms. Since speed and distance is linear, for her to not hit the bullet, she would have to travel less than 30mph. I would say 25mph to be safe which is the speed of a bicycle race on flat surface.

For this we can say for Nagato's own safety, she will need to slow down for her special attack.

someone better at trig can check my math, I haven't touched it for decades.
