What would make a car shakes between 40 and 60 miles per hour only during acceleration?

depending on how fast you accelerate, you get worse/better mpg a slow acceleration produces better mpg than a faster acceleration.

No. "Miles per hour" is a speed. An acceleration might be "Miles per hour per hour", or "miles per hour squared".

Acceleration = velocity change / time A = (v2 - v1) / t A = (15 - 5) / 6 = 10 / 6 = 1.66667 miles per sec2 (miles per sec. per sec.)

negative one mile per second per second

There is no acceleration if the car is travelling at a steady 54,000 miles per hour.

Acceleration = (change in speed) divided by (time for the change) Acceleration = (25 - 0)/(3) = 81/3 miles per second2 Don't try this at home. That acceleration is about 1,368 G's. You can not survive it!

Force is mass X acceleration. means that the speed miles its = to miles.

Constant velocity is a measure of distance traveled per unit of time at a uniform speed, such as miles per hour or feet per second. Constant acceleration is a measure of a continuing increase in velocity per unit of time, as when a car speeds up from 30 miles per hour to 40 miles per hour in 5 seconds, then from 40 miles per hour to 50 miles per hour during the next 5 seconds. It will then have had a constant acceleration of 10 miles per hour per 5 seconds.

Acceleration = change in velocity/change in time Acceleration = 96 miles per second - 32 miles per second/8 seconds = 8 miles per second per second or, better expressed 8 mi/s^2 ---------------

If its speed is constant, its acceleration is nil.

Constant velocity=no acceleration.

Well, first of all, "miles per second" is a speed, not an acceleration. I'll fix it and make it an acceleration, in order to go on and find an answer. Call the acceleration 322 miles per second2 . 322 miles/second2 = 518,208.8 meters/second2 Force = (mass) x (acceleration) = (0.9) x (518,208.8) = 466,388 Newtons (rounded) That's the same as about 104,844 pounds . . . an awful lot of force, but the really amazing part is the tires that can hold the track with that kind of torque.

20 miles/hour/second The acceleration is simple division 60/3 = 20.

Acceleration = -20 mi/h^2

You have a wheel out of balance more than likely.

Average acceleration = change in velocity/change in time A = 300 mi/s - 200 mi/s/20 s - 0 s Acceleration = 5 miles per second squared ==============================

Since acceleration is a change in velocity, if your velocity is constant (does not change), your acceleration is zero.

Rule: Magnitude of acceleration = Change of velocity / Time interval In linear motion, magnitude of acceleration is the measurement of change in speed in speed per unit time. For example: A car reaches a speed of 20 miles per second in 4 seconds, the magnitude of acceleration is 5 miles per second. a = 20 miles/second divided by 4 seconds = 5 miles per second. Acceleration is a vector, which means it has magnitude and direction. To describe accelerated motion completely, the direction also needs to be included. So it would be 5 miles per second in whatever direction it is going.

It might be your transmition...

9.8 miles/sec2 = 1,609.3 times the acceleration of gravity

Once reaching 90 the if speed is constant thee is no acceleration; to get to 90 you need to know time as speed = acceleration x time

The average professional midfielder runs between 5 and 7 miles.

-66.667 miles per second squared

A gain of 2 miles per second squared

Assuming that the rate of acceleration is constant and 8 miles per second2 NOT 8 miles per second, as stated, then v2 = u2 + 2as where v = final velocity = 64 mph u = initial velocity = 0 mph a = acceleration = 8 miles/s2 s = distance travelled (in miles) so s = (v2 - u2)/(2a) = 64*64/(2*8) = 256 miles.
