"shallow staging" can therefore get almost a free foot of untimed acceleration before the clock officially starts, effectively achieving a rolling-start velocity of 3-5 mph and shaving the 0.3 second it typically takes to cover that distance off his elapsed time (ET) … rollout with 0-60 times is inappropriate in our view. … begun publishing ...
The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). [1] It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). [2] The corresponding unit in the International System of Units (SI) is the meter per second.
second (SI base unit) s ≡ Time of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom at 0 K [8] (but other seconds are sometimes used in astronomy). Also that time it takes for light to travel a distance of 299 792 458 metres. (SI base unit) shake ...
For example, Bob Hayes won the 100 meters in a FAT time of 10.06 seconds, which was converted to an official time of 10.0 seconds: the FAT systems in 1964 and 1968 had a built-in 0.05 second delay, meaning Hayes' FAT time was measured as 10.01 seconds, which was rounded to 10.0 seconds for official purposes (despite the fact that officials with ...
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
ft/s 3.2808 The metre per second is the unit of both speed (a scalar quantity ) and velocity (a vector quantity , which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second .
The length unit of the system is the furlong, the mass unit is the mass of a firkin of water, and the time unit is the fortnight. [ 1 ] [ 2 ] Like the SI or metre–kilogram–second systems, there are derived units for velocity , volume , mass and weight , etc.
Miles per hour (mph, m.p.h., MPH, or mi/h) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour. It is used in the United Kingdom , the United States , and a number of smaller countries, most of which are UK or US territories, or have close historical ties with the UK or US.
