	Latitude-Longitude Conversion to Feet
		A minute of latitude is equal to one nautical mile, or 6076 feet; thus, a second of latitude (6076 divided by 60) is 101 feet, 3 inches.
		Conceptually and practically, latitude is the same no matter where you go on earth; however, in reality it varies from 69.41 statute miles per minute at the poles to 68.70 statute miles per minute at the equator due to the earth bulging slightly from its rotational spin.
		Finally, 60 degrees North (southern border of the Northwest Territories), a degree of longitude is 34.67 statute miles, 3051 feet (930 meters) per minute, 50.85 feet (15.5 meters) per second.

	G1681 Measuring Irrigation Water in a Ditch, Stream or Reservoir, MU Extension
		One cubic foot per second is a flow of water equivalent to a stream 1 foot wide and 1 foot deep flowing at a velocity of 1 foot per second.
		Multiply the velocity in feet per second by the estimated stream cross-sectional area in square feet to determine the flow rate in cubic feet per second.
		A second method is to measure the depth of water next to the weir, but far enough to the side of the crest to be in still water.

		We conclude that the average velocity from.5 to 1 second after throwing the ball upwards at 64 feet per second, is 40 feet per second.
		The units for the derivative are feet per second, the units of s divided by t.
		This instantaneous velocity at 1 second is less than the average velocity from.5 to 1 second that we computed in the first part of this problem because the ball is slowing down under the influence of gravity from.5 to 1 second.

		One cubic foot per second is equal to the discharge through a rectangular cross-section one foot wide and one foot high, flowing at an average velocity of one foot per second.
		It is measured in feet for a given quantity of water pumped during a specified period, or after the pumping level has become constant.

		The negative sign indicates that it is headed in the negative direction, and it is moving backwards at a rate of one foot per second.
		The acceleration is 2, which means that at that instant, its velocity is increasing by a rate of 2 feet per second each second.
		For example, if the velocity of an object is -3 feet per second, then that object is moving backwards (direction) at a rate of 3 feet per second (magnitude).

	Simple Gliders in the Science and Mathematics Curriculum
		To convert feet per second to miles per hour, you convert feet to miles by dividing by 5,280 and convert per second to per hour by multiplying by 3,600.
		The speed in miles per hour will always be less than the speed in feet per second by the same ratio, so you can convert speed in feet per second by dividing it by 22 and multiplying it by 15 to get miles per hour.
		It is a speed and is measured in feet per second.

	Optional Archery Rules
		Since trajectory is directly related to arrow speed, the slower an arrows’ speed per second, the more curved its flight path must be to hit a far off mark.
		Still, to simulate some of the thought processes required in calculating curvaceous trajectories, a GM could impose the rule that if the target is beyond the maximum effective range of the bow, then the archer must spend one action mentally considering the much altered arc of his arrow before he fires it.
		Due to its specific features, the arrow receives a +70 feet to its range and a +1 damage (total damage from the combined base damages of the bow and arrow is 3D6+1).

		The word `per' or a slash between two units denotes division, so that `Joules/second' and `Joules per second' denote Joules per second.
		If units does not rec- ognize a unit name, and the name ends in the letter `s', units discards the `s' and tries again, so that `meters' is the same as `meter' unless there is a separate defin- tion of `meters'.
		If the two units you enter don't have the same dimension (``How many acres are in a second?''), units prints the message conformability (Not the same dimension) and then prints the internal forms of both units of mea- surment, to show what it thinks they are defined as.

		Common units are cubic feet per second (cfs), second-day feet (sdf), and cubic meter per second (cms)."
		The USGS defines cubic foot per second (cfs) as "the flow rate or discharge equal to one cubic foot of water per second or about 7.5 gallons per second."
		Side tributaries also vary due to seasonal changes or storm events; many tributaries will be dry much of the year but potentially brim with thousands of cfs of water and debris in the event of a major flood.

	TRAJECTORIES AND ORBITS
		Before launching, the vehicle is at the Earth's distance from the Sun, moving with the Earth's speed around the sun-about 100,000 feet per second.
		Starting from the surface of the Earth, a launch velocity of about 54,000 feet per second will lead to escape from the solar system The course of the vehicle will be a parabola, with the Sun at its focus; until eons later lt is deflected by some star or other body.
		One kind of application of particular interest involves use of heavy conventional propulsion systems to develop orbital velocity (say, 25,000 feet per second) and then to build up the remaining 12,000 feet per second to reach escape velocity by a low-thrust electrical system.

	Naturally Accelerated Motion
		This means that after two seconds it would be moving at eight feet per second, after three seconds at twelve feet per second and so on until it hits the end of the ramp.
		But it can't have gotten that far after two seconds, because it just attained the speed of eight feet per second when the time reached two seconds, so it was going at slower speeds up to that point.
		We found that, approximately, the rate of increase of speed was ten meters (1,000 cms) per second in each second of fall, so after half a second it was moving at about five meters per second, and after a quarter of a second it was going two and a half meters per second.

		There are 3600 seconds in 1 hour so hours/second = 1 hour/3600 seconds which means: 55 miles 1 hour 55 miles -------- x -------- = -------- 1 hour 3600 sec 3600 sec Now, what would you multiply miles/sec by to get feet/sec?
		There are 5280 feet in 1 mile so feet/mile = 5280 feet/1 mile which means: 55 miles 5280 feet 55 x 5280 feet -------- x --------- = -------------- 3600 sec 1 mile 3600 sec This works for any conversion.
		In this particular instance, as a check, you can use the fact that 60 miles per hour is the same as 88 feet per second.
