How is speed calculate?

Average speed is calculated by dividing the total distance covered divided by the time taken. Instantaneous speed is calculated as the derivative of displacement with respect to time.

What is a 1986 IROC Z camaro's top speed?

about 117mph on a trailer behind a dodge pickup

To the dingbat who posted that - what is wrong with you? We have both the Iroc and a Dodge ram WITH A HEMI. For kicks we took them out on the road and RACED them - I'm sorry to inform you that the Iroc-Z SMOKED our Hemi Dodge Ram truck (it's a 2007 - brand new o.k.). Oh, my husband's Iroc-Z actually does 154 - I've seen it myself driving the car. SORRY! LOL

Heh, 154. Right... And I'm guessing that you wax it weekly, and this keeps cops' RADAR guns from working, because it's got "Such a sweet shine" to it as well?

How many times bigger is a kilometer per hour than a meter per second?

a little maths going on...

well, this is maths. lol

didnt quite get your question but....

1km/hour and 1m/second

say you have 10km/h

lets put this in m/s

so 10km are 10000m and 1 h is 3600s, so 10km/h are 10000m/3600s = 2.7777m/s

So 10km/h are 2.777m/s In this case km/h is 10/2.777 times bigger than m/s = 3.6 times bigger.

But take another example!

20km/h lets put this in m/s

So 20km are 20000m and 1h are 3600s, so 20km/h are 20000m/3600s = 5.555m/s

So 20km/h are 5.555m/s In this case km/h is 20/5.555 times bigger than m/s = 3.6 times bigger.

Hey, it gave us the same, so with two examples I came to a conclusion that 1km/1h is 3.6 times bigger than 1m/1s

Hope I'm not wrong, but try to do some more examples by picking any number. Good luck and hope I helped!! :)

Well like i said one time what does this mean

No offense, but I'm not quite sure why you made it so complicated. Also, a meter per second is faster than a kilometer per hour. Try it this way:

In one hour, you go 1000 meters, am I correct? So how many meters can you go in an hour at 1 meter per second? Well, there are 3600 (60 seconds in a minute x 60 minutes in an hour) seconds in an hour, so you can go 3600 meters. Therefore, traveling at a meter per second is 3.6 times faster than traveling at a kilometer per hour. Same answer, just switched around and made simple.

Does your heart beat faster when you do a headstand?

No, and yes.

according to physics, Vertical motions is to be consider _ Zero work as long at the motions stays in the vertical line.

Basically The amount of energy used to stand up would be equivalent the same to do a headstand. The equal amount of energy would covert both ways in a zero work ratio.

However is your energy is used to go up and down against the vertical alignment , like doing headstand pushups your are doing work because your body itself is going against the plains of "normal motion" causing energy.

In lamen turns- being still vertical in a mirror shape doesn't incrase your heart rate but goign up and down does.

Kinematics equations are used only by physicists and people who work in space.?

No, it is also used by students taking Physics and their professors.

You can use kinematics to find a shortcut (resultant vector) on how a plane or ship moves. You can use robot kinematics to find how a robotic arm will move. You can use it to study how particles move. You can use linear kinematics to discuss how a football player moves across the field. You can use it to design a track for a Hot Wheels racecar to go on.

***

Kinematics equations are used in LOTS of professions. For example, a person investigating a car accident to determine fault could use kinematics, dynamics and momentum equations to evaluate the claims of each driver (as to initial speed or coming to a full stop at a stop sign) from skid marks, final distance & direction from the point of impact.

How fast does a f1 car accelerate from 0 to 100 km per hour?

0 to 100 km/h (62 mph): 2.0 seconds

0 to 200 km/h (124 mph): 3.9 seconds

0 to 300 km/h (186 mph): 8.6 seconds

What is the dimensional formula of energy?

the formula to find specific heat is

specific heat= calories/mass X change in temperature.

How many feet per second does a car travel going 30mph?

30 mph = 30*5280 feet per hour = 30*5280/3600 feet per second

= 44 feet per second

(The conversion factor from mph to fps is 22/15)

What quantity is the sum of the kinetic energy and all forms of potential energy in a system?

The sum of kinetic energy and potential energy in a system is the total mechanical energy of the system. This total mechanical energy remains constant if only conservative forces are acting on the system, according to the principle of conservation of mechanical energy.

Why is velocity tangential to the path of a body?

Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.

Explain why when a ball is dropped from a height its speed increases?

The ball experiences the force of gravity which pulls it towards the centre [of mass] of the earth. According to the essence of the second of Newton's Laws of Motion, a force acting on a body accelerates it in the direction of the force. Thus, the ball speed up towards the centre of the earth.




Whenever there is a force - in this case gravity - there will be an acceleration. (To be precise, a NET FORCE is required to provide acceleration.) According to Newton's Second Law, the acceleration is equal to the force divided by the mass.

What is acceleration and velocity?

Acceleration and velocityVelocity - which is not quite the same thing as speed -- is the measure of the rate of change in position. In other words, to calculate velocity, we divide the change in an object's displacement -- how far it moved -- by the time it took to move. If an object moves, say, 100 feet in 10 seconds, its velocity is 100/10 = 10 feet per second (ft/s).

Acceleration is the rate of change of velocity. If an object increases its speed from, say, 10 ft/s to 60 ft/s in five seconds, its acceleration is 10 feet per second per second, or 10 feet per second squared (ft/s2).

How did we arrive at that figure? Divide the change in velocity by the change in time. The change in velocity is 60 - 10 = 50 ft/s. The change in time is 5 - 0 = 5 s. Hence, 50/5 = 10 ft/s2.

How far does a plane fly in 15 s while its velocity is changing from 145 to 73 at a uniform rate of acceleration?

Since the acceleration is uniform you can add the starting and ending velocities and divide by two the average speed

145 + 73 = 218

218/2 = 109 (units not given so I assume Miles per Hour)

To convert to Feet per seconds

109 mph X 5280 feet in a mile / 3600 seconds in an hour = 159.866667 feet per second

multiply the above by 15 seconds and you get 2398 feet

What is subsonic sound?

Another term for this is infrasonic, and it means pertaining to below hearing. There natural frequencies that humans can hear which are high: 20,000 Hz and low: 20 Hz. An average human cannot hear sounds below the frequency of 20 Hz. That is subsonic. Subsonic is a term also applied to aircraft that travel at speeds less than the speed of sound. Supersonic means it travels faster than the speed of sound.
