A bullet is fired from a gun. The speed of the bullet will be about the same as the speed of the recoiling gun if the mass of the bullet equals the mass of the gun
The mass of a bullet is nowhere near the mass of a gun. A bullet
weighs at most a few hundred grains. Most guns weigh at least a
couple of pounds, some weigh several pounds (talking about handguns
and rifles).
What is the relationship between wavelength wave frequency and wave velocity
wave velocity (m/s) = frequency (Hz) x wavelength (m) wavelength
= wave speed / frequency frequency = wave speed / wavelength
