G-Force in Motorcycle Accident from 30mph to 0mph

[claracatrye]

Can anyone tell me what G force would be received when going from 30mph to 0mph in 0feet. This is from involvment in a road traffic accident on a motorbike. Thanks

You mean that you decelerate from 30mph to 0mph traveling 0 ft. This will make acceleration undefined (or infinity if you like it).

In a motorcycle crash you don't decelerate in 0 feet. When the crash first occurs, the front of the bike starts to stop. The rest of the bike and the rider continue to go forward. This usually results in the bike crumpling, bending, etc as it absorbs energy from the impact. The rider is usally thrown off. Also, whatever it crashes into experiences the same thing.

The acceleration would be infinite and the force required to do this would be infinite. This doesn't happen.

Even if a steel block hits a solid steel wall, something WILL bend or deform some non-0 value, no matter how small, to provide a non-0 stopping distance.
