What describes a trains acceleration if you changes speed from 25 miles per second to 10 miles per second in 240 seconds?
acceleration = change in speed /time = (10-25)/240=15/240 = -1/16
The train is slowing down (decelerating) at a rate of 1/16 mile per second per second
Added:
Hate wasting work! Same answer in decimal.
Acceleration ( looks like slow down here ) = change in velocity/change in time
10 mi/s = 25 mi/s/240 s - 0
= - 0. 0625 mi/s2
======================long time braking
What else can I help you with?
An object's velocity changes from 30 meters per second to 23 meters per second in 3 seconds What is is its acceleration?
-2.33 metres per second squared
What is the acceleration of a car that goes from 32 miles per second to 96 miles per second in 8 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 ---------------
A train approaching a crossing changes speed from 25 meters per second to 10 meters per second in 240 seconds how can the train's acceleration be described?
Acceleration = (change in speed) / (time for the change)= (10 - 25) / 240 = -15/240 = -0.0625 meter/sec2The acceleration is negative, which is a description of slowing down.
What is the acceleration of a sprinter that runs a race in 12 seconds and finishes the race traveling 24 meters per second?
The sprinter's acceleration is 2 meters per second squared.
The velocity of an object goes from 4 m per second to 12 m per second in 4 seconds what is its acceleration?
The change in velocity was 8 m / s. Divide that by 4 seconds and get 2 m / s2 -- sometimes stated as acceleration of 2 meters per second per second.
An object's velocity changes from 30 meters per second to 23 meters per second in 3 seconds What is is its acceleration?
-2.33 metres per second squared
Which describes an object and velocity that changes by the same amount each second?
An object with a constant acceleration will have its velocity change by the same amount each second. The acceleration remains constant, causing a uniform increase or decrease in velocity over time.
Which describes an object's velocity that changes by the same amount each second?
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
Ten meters per second squared describes what?
The acceleration of gravity.
If speed is measured in meter per second and time is measured in seconds what is the Si unit for acceleration?
It is metres per second per second or metres per second squared.
A car accelerates to pass a truck going from 20miles per second to 29miles per second in 3 seconds what was the acceleration?
So acceleration is an increase of speed every second. The increase of speed was 9miles/sec and this was over 3 seconds. Therefore there was an acceleration of 3 miles/second every second i.e. 3m/s2
Why seconds are s2 (squared) in the acceleration formula?
Seconds are not squared in the acceleration formula. The units for acceleration are meters per second squared (m/s^2), where the time unit (seconds) is squared to represent the change in velocity over time.
What is the acceleration of a car that goes from 32 miles per second to 96 miles per second in 8 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 ---------------
A train initially stationary has a constant acceleration of 0.5 Miles per second what is the speed after fifteen seconds?
After 15 seconds, the train's speed would be 7.5 miles per second. This can be calculated by multiplying the acceleration (0.5 miles per second) by the time (15 seconds).
A train approaching a crossing changes speed from 25 meters per second to 10 meters per second in 240 seconds how can the train's acceleration be described?
Acceleration = (change in speed) / (time for the change)= (10 - 25) / 240 = -15/240 = -0.0625 meter/sec2The acceleration is negative, which is a description of slowing down.
The phrase''ten meters per second squared'' describes the?
Acceleration of the object.
