Re: Iran: Passenger Crushed By Drifting Car
sorry, but that ain't drifting drifting is in a rear wheel drive, steering via the throttle - that was just morons pushing a sewing machine around in circles until it falls over  |

Re: Iran: Passenger Crushed By Drifting Car
Awww only got to see him flail a little bit. What was the point if this event? Show off your poverty? |

Nothing like starting your day with 2 tons of car falling on your napper.  |

That looks like it hurt Allah-t.

Wearing a mask would have prevented that.

Re: Iran: Passenger Crushed By Drifting Car
I keep trying to turn this into a physics question: Was the length of the slide increased or shortened by adding a human body between the car and the pavement?  |

Re: Iran: Passenger Crushed By Drifting Car
Aw too bad we didn't get to see more of the twitching... should be the best part! Great vid though!  |

Re: Iran: Passenger Crushed By Drifting Car
The long answer would be: The friction force that is required to stop that clunker would be equal to its kinetic energy Let's say the car weighs 2,000 Kg The kinetic energy of the car is KE= 1/2 m v2 where: KE = Kinetic energy of the drifting car m = mass (kg) v = velocity (m/s) KE = 1/2 (2000 kg) ((100 km/h) (1000 m/km) / (3600 s/h))2 = 771605 J The friction energy needed to stop the car can be expressed as FE=FF SD Where FE= Friction energy to stop the car (Joules) FF= Friction force (Newtons) SD= Stopping distance (m) Since the kinetic energy of the car is transformed into friction energy, we can say: KE = FE To calculate the friction force FF FF = μ m g Where: FF= Friction force μ - Friction coefficient (0.6 for dry concrete) m = Mass of object ag = Acceleration of gravity = 0.6 (2000 kg) (9.81 m/s2) = 3924 N So the distance would be d=FE/Ff d=771605 J/3924 N = 197m Now considering the following kinetic friction coefficients for rubber on dry and wet concrete On dry concrete & rubber μ=0.6 - 0.85 11,772 N - 16677 N friction force On wet concrete & rubber μ=0.45 - 0.75 8829 N - 14715 N friction force We can conclude that the needed distance would be longer for lower friction coefficients, we can confidently assume that the body under the car is turned to a mushy wet goo, hence the car would be sliding an a wet mushy substance and that only means a longer distance would be needed for the clunker to get to a stop.  |
