no it is not, velocity includes speed and direction and while the speeds are the same the direction is not
No. Velocity is described as a speed in a certain direction. Since they are in different directions, they are different velocities.
The British Rail can only hold up too 477 tons. This is a train that was built in 2002.
Generally Yes. But that also depends on how you define V6. Becasue a Porsche is a flat 6 and those things can top 300kmh.
yes. Formula ones have to stop in distances of less than 150m from over 300kmh whereas nascars just crash when they try that. Thats why nascars great to watch.
The 186mph (300kmh) limit was self-imposed by the motorcycle makers a few years back when it became obvious that motorcycles could easily become way to fast for their own good. Companies still get around this by making bikes like Suzuki's Hayabusa, which reaches almost 200hp and more than 185mph with a very conservative fuel injection mapping, restrictive air cleaners, and a stuffy road-legal exhuast. A mechanical-saavy owner can easily remove and alter these parts to make a bike that is capable of well over 200mph.
