WebFeb 19, 2016 · A stopping distance is then x 0 = v 0 τ. you need a magnetic field: B = ζ ρ v 0 / x 0. For a lead bullet, ζ = 22 ⋅ 10 − 8 Ω m, ρ = 11.3 ⋅ 10 3 k g / m 3. To stop a bullet in x 0 = 1 m long distance, starting at typical velocity v 0 = 300 m / s, you need B = 0.9 T. A large, but still reasonable field, but not entirely crazy - it can ...

WebThe kinetic energy of the bullet is $\frac12 mv^2 \approx 1$ kilojoule. Spreading the bullet's energy over the stopping time gives an average power of 175 kilowatts. If you make some hand-waving assumptions that the mechanism for stopping the bullet is inefficient you might multiply this power by a factor of 10–100. This is a lot of power!

For a bullet, one estimate that I have read for terminal velocity is around 300 ft/sec (about 200 mph). Since that’s a lot slower than a bullet leaves a gun nozzle, it seems that the air resistance really will have a big effect on the speed of the falling bullet. how far is 800 kilometers in miles
