How many feet can a person run in a second?
The 'second' referred to is in reference to Degrees Minutes & Seconds Such As:
N 11°22'33" E (example) Where the 33" is the "Seconds".
However in the case listed above, the Degrees, minutes, and Seconds refers to a direction and not a distance. The appropriate answer to the question refers to Latitude and Longitude, where you will express the degrees, minutes, and seconds as a distance rather than a direction and will appear similar to this:
11°22'33" N, 11°22'33" W (example)
Answer in this scenario:
A degree is about 69 miles. Divide that by minutes and find that there is about 1.15 miles in a minute. Divide that by 60 and you will find that there is about .019 miles in a second. Since there are 5280 feet in a mile, multiply .019 by 5280 to get about 101.20 feet in a second.
There are APPROXIMATLEY 101.20 FEET in a second.

What are examples of low friction materials?
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.
If you can run 15 mph how fast would that equate into a 40 yard dash time?
To convert speed (in this case, 15 mph) to time taken to run a specific distance (40 yards), you need to first convert the speed to yards per second. Since 1 mile is approximately 1760 yards and 1 hour is 3600 seconds, 15 mph is equivalent to 22 yards per second. Therefore, to cover 40 yards at a speed of 15 mph (22 yards per second), it would take approximately 1.82 seconds (40 yards divided by 22 yards per second).
In some newer coaster designs, a catapult launch sets the train in motion. There are several sorts of catapult launches, but they all basically do the same thing. Instead of dragging the train up a hill to build up potential energy, these systems start the train off by building up a good amount of kinetic energy in a short amount of time.
How many mph is 13.1 in 100 meter?
Oh, dude, you're mixing up your units there! 13.1 miles per hour is how fast you'd be going if you covered 100 meters in one hour. But if you want to know how many mph is equivalent to running 100 meters in 13.1 seconds, you'd need to do some quick math to convert that time to hours first. Like, whoa, slow down, we're not in a race here!
What are non examples of net force?
A net force is the vector sum of ALL forces acting on a given object. A "non-example" would include an individual force, when there are other forces involved. For example, if you have a book on a table, the downward force of gravity is NOT the net force, since there are other forces involved.
Compare and contrast the energy processing organelle?
Mitochondria are responsible for generating energy in the form of ATP through aerobic respiration, while chloroplasts are responsible for converting light energy into glucose through photosynthesis. Mitochondria are found in nearly all eukaryotic cells, while chloroplasts are found only in plant cells and some protists. Both organelles have their own DNA and ribosomes, suggesting they have bacterial origins.
How fast in KMH is 25 Horsepower?
The question, as stated, cannot be answered sensibly. A kilometre per hour is a measure of speed, with dimensions [LT-1]. A horsepower is a measure of power, with dimensions [ML2T-3]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
You cannot directly convert cubic centimeters (cc) to miles per hour (mph) as they are measuring different things (volume vs speed). You would need additional information related to the vehicle's engine displacement and speed to calculate mph.
Oh honey, you're mixing apples and oranges here. 2.4GHz is a measure of frequency, not speed like mph. It's like asking how tall a banana is in pounds. Just focus on enjoying your gadgets and let the mph be for cars, okay?
What is the formula for time when velocity and mass are given?
The formula for time when velocity and mass are given can be derived using the equation for momentum. Momentum is defined as the product of an object's mass and velocity. Therefore, the formula for time can be expressed as time = mass / velocity. This formula allows for the calculation of time based on the known values of mass and velocity.
Oh, dude, let me break it down for you. So, Vintland takes 15 hours to make a bottle of wine, while Moonited Republic only takes 10 hours. So, Moonited Republic has the absolute advantage in making wine because they can whip up those bottles faster. It's like a race to the wine finish line, and Moonited Republic is already popping the cork while Vintland is still uncorking the bottle.
What does kinetic energy and potential energy have in common?
History
A roller coaster train going down hill represents merely a complex case as a body is descending an inclined plane. Newton's first two laws relate force and acceleration, which are key concepts in roller coaster physics. At amusement parks, Newton's laws can be applied to every ride. These rides range from 'The Swings' to The 'Hammer'. Newton was also one of the developers of calculus which is essential to analyzing falling bodies constrained on more complex paths than inclined planes. A roller coaster rider is in an gravitational field except with the Principle of Equivalence.
Potential Energy
Potential energy is the same as stored energy. The "stored" energy is held within the gravitational field. When you lift a heavy object you exert energy which later will become kinetic energy when the object is dropped. A lift motor from a roller coaster exerts potential energy when lifting the train to the top of the hill. The higher the train is lifted by the motor the more potential energy is produced; thus, forming a greater amount if kinetic energy when the train is dropped. At the top of the hills the train has a huge amount of potential energy, but it has very little kinetic energy.
Kinetic Energy
The word "kinetic" is derived from the Greek word meaning to move, and the word "energy" is the ability to move. Thus, "kinetic energy" is the energy of motion --it's ability to do work. The faster the body moves the more kinetic energy is produced. The greater the mass and speed of an object the more kinetic energy there will be. As the train accelerates down the hill the potential energy is converted into kinetic energy. There is very little potential energy at the bottom of the hill, but there is a great amount of kinetic energy.
Theory
When the train is at the top and bottom of the hill there is not any potential or kinetic energy being used at all. The train at the bottom of the first drop should have enough energy to get back up the height of the lift hill. The "Act of Faith" in riding these amazing rides which seems more of a phenomena that is only a theory. In practices, the train never could make it back up the hill because of dissipative forces. Friction and air resistance, and even possible mid-course breaks, are dissipative forces causing the theory to be changed but not destroyed. These forces make it impossible for the train to have enough energy to make it back up the lift hill's height. In the absence of the dissipative forces the potential and kinetic energies(mechanical energy) will remain the same. Since the mechanical energy is destroyed by the forces, the first hill is always the highest

What is a Newton-Meter per second squared?
Oh, dude, a Newton-Meter per second squared is just a unit of measurement for force. It's like when you're calculating how much oomph something has when it's accelerating. So, basically, it's the fancy way of saying how hard something is getting pushed or pulled over time.
Where is there a job that pays 10.00 per-hour that is close to you and you only have to be sixteen?
No where. Most 16 year olds do not have the qualifications to earn $10hr.
How many feet per second do you have to be traveling to be going 55 mph?
55 mph equals 80.66 feet per second
That would be referred to as a "speed".
It can also be described as "45 miles per hour", to which it is identically equivalent.
