Ok, yesterday 蘋果日報 Headline was a traffic accident on the 青衣北橋 Tsing Yi North Bridge.
The report was that a truck had a minor accident first and collided with a barrier. One of the passengers got off and checked the damage. Then they chose to flee the scene.
About after 800m of driving, they struck the lane partition and got killed in a second accident.
Now... The truck supposedly was travelling at 140 km/h when it struck the partition the second time that led to the fatal mistake.
Now my question is... One of these trucks not carrying cargo, could they accelerate to 140km/h from a standing start with 800m?
I would appreciate it greatly if someone out there can answer me. What would the acceleration be? (I have long given back nearly all my differentiation back to my calculus teacher) 0 - nearly 100mph in 800m... Is it possible?
