How fast is 250 kilometers per second?
Speed is always relative.
250km / sec is very fast however when compared to normal everyday human things. It means that in just 1 second something has travelled 250,000 metres.
It helps to think of this relative to something else. The Earth is about 40,000km around the equator. So at this speed you could do a complete lap of our planet in 40,000 / 250 = 160 seconds (2 minutes 40 seconds). As you can see, this speed is fast.
However there are things which travel faster than this. Light travels about 1200 times as fast as this! Light could do a lap in about 0.13 seconds.
The only shape whose area you know how to calculate is a rectangle, so you draw
a bunch of skinny rectangles with one end of each rectangle on the speed-graph.
The more rectangles you draw and the skinnier they are, the more accurate your
calculation will be. The whole idea behind one of the main divisions of Calculus is
how to do this in such a way that the width of the rectangles shrinks to zero and
the number of them becomes infinite, so the area calculation becomes exactly right.
That's the part of math called "Integral Calculus", and you're thinking close to it now.
You're gonna have a lot of fun with it in just a few years if you stick to your math.
What does 3000 kcal per hour mean?
References for Calorie (kcal) Values The values shown below for the approximate Calorie (kcal) expenditure of walking are based on the MET values provided by Ainsworth in The Compendium of Physical Activities Tracking Guide. Calculations that include ascending and descending flights of stairs also utilize the approximate kcal values provided by Taylor in Guthrie and Picciano. Calculations for "Additional Calories Burned" and "Weight Control Benefit" are informed by Guthrie and Picciano. http://www.wv-hsta.org/cdc_chc/walking_kcal_expenditure.htm
33 knots is approximately equal to 37.98 miles per hour (mph).
How do you find distance with uniform velocity time final velocity and initial velocity?
If the velocity is uniform, then the final velocity and the initial velocity are the same. Perhaps you meant to say uniform acceleration. In any event, the question needs to be stated more precisely.
From the information provided it is impossible to answer the question. You require the velocity or speed of the ball and that is not measured in milliseconds - which a measure of time!
On the graph of a waveform time is represented along which axis?
Time is plotted on the horizontal axis.
A bowling ball is going 15miles per hour how fast is it going in feet per seconds?
15 miles/hour (5280 feet/1 mile)(1 hour/3600 seconds)
= 22 feet per second
Actually, the opposite of Kinetic is Static. Kinetic means "in motion", static means "not moving".
How fast does a cheater run in mph?
If you are prepared to cheat, you can claim that you travelled at any reasonable speed.
What makes a Pontiac montana shake at 45 mph?
It is possible that the shaking in a Pontiac Montana at 45 MPH is the result of failing bearings or tie rod ends.
You can calculate the magnitude of the displacement by using Pythagoras's Theorem.
a2+b2=c2
Let a be 8, b be 6 and c be the magnitude.
8km2+6km2 = c2
64k+36km = c2
100km = c2
10km = c
the velocity at the start is the same as when it comes back down to the level. At the top velocity is zero and at the bottom the velocity is acceleration x time where time is 1.37/2 = 0.685s. Acceleration is that of gravity or 9.8 m/s/s, so projectile velocity is 9.8 x .685 = 6.7 m/s; in US system that is 22 ft/sec or 15 mph
What velocity if a body strike the ground which was dropped from the height of 176.4m?
The formula for a socalled "free fall" velocity (v in m/s) is:
v = SQRT [2.g.h]
in which g = 9,81 m/s2 (mean gravitational accelleration on earth) and h is the falling highth in metres.
Calculating: v = SQRT[2 * 9.81 * 176.4] = SQRT[3461] = 58.8 m/s
So, ONLY if no resistance (eg. from air) is conteracting the force by gravity, then the velocity at ground level will be 58.8 meter per second and by then this is also independent from the falling mass (theoretically).
However, depending on measures, mass and surface area and roughness, the air resistance can play a major role in decreased veleocity: look at hail, rain drops, and fogg: same density, different surface, and fogg will never reach ground (!), but I would like to miss being bombed by large hail stones from 150 m high!
Can the 2004-2007 Toyota Prius speedometer be switched from MPH to KPH?
Yes, at the simple push of a button on the dash.
How do you calculate ultimate moment of resistance?
we can find the
ultimate moment of resistance by in case of hand lever by following
length of boss.thickness of boss.tensile stress.(distance from outside of the object concerned to the major axis)
How do you find kinetic energy if no final velocity is given?
You can calculate kinetic energy using the formula KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity. If the final velocity is not given, you would need more information or assumptions to solve for kinetic energy.
When did the potential energy of the ball begin to change to kinetic energy?
when the position of the BALL is changed WITH RESPECT TO HEIGHT then P.E change in to K.E
No, gravitational portential energy is more with more hight and gravitational kinetic energy is maximum just before reaching the ground.
If a car is going 27 miles per hour how many meters will it travel in a minute?
To convert miles per hour to meters per minute, first convert 27 miles per hour to meters per hour by multiplying by 1609.34 (1 mile = 1609.34 meters). Then divide this value by 60 to get meters per minute. Therefore, a car going 27 miles per hour will travel approximately 24.14 meters in a minute.
Did chuck norriss do the fasted kick once 60 mph?
i think chuck norris did the first fasted kick at 60 mile per hour
