Reaching around 81 mph, theDaihatsu Hijet truckis in the second position on this list. The speedometer seems to say they’re good to about 140 km and Googling reveals they’re good to about 80 mph, which would check out on the 140kph speedometer. Having a long history from 1960, now t...
The speed limit on some interstate highways is roughly 120 km/h. What is this in meters per second? How to convert kph to mph with a formula A car is traveling at a speed of 8 m/s. It accelerates to a speed of 11 m/s in 7 seconds. Calculate the (a) acceleration of the...
California made many other errors, but its decision to get single-deck trains is correct in its use case: the high-speed trainset market is almost entirely single-deck, and the issue of platform length is not relevant to captive high-speed rail since the number of stations that need high-...
A hard-disk platter can spin underneath its head at speeds up to 3,000 inches per second (about 170 mph or 272 kph)! The information on a hard disk is stored in extremely small magnetic domains compared to a cassette tape's. The size of these domains is made possible by the precision...
I don't drive too often in the city (and not at all in Boston..), but when I do, I usually am at the speed limit or above. Most of my driving is done on the interstate, where I'm definitely going above 15mph above the 65mph limit. It's hard to get a real average ...
Hurricanes have maximum sustained winds — the highest one-minute average wind speed at a particular point in time — of 74 mph (120 kph) or higher. If a tropical cyclone has maximum sustained winds between 39 and 73 mph (63 kph to 120 kph), it is called a tropical storm. If maximum...
Jet plane comes in for a landing with a speed of 120 m/s. The length of the runway is 500 m. From the instant ne plane touches the runway, 1. What is the acceleration needed to stop within the runway? An airplane goes from 0 ...

Velocity and speed are often used interchangeably in everyday language, however there is a distinction in physics. Velocity is a vector, which means it has magnitude and direction. It is calculated using displacement, which is the straight line distance from start to finish ...
Dynamo lighting is reliable, durable, environmentally friendly, more difficult to steal, and extremely convenient.
