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
-2.33 metres per second squared
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.
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 ---------------
The sprinter's acceleration is 2 meters per second squared.
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.
-2.33 metres per second squared
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
The acceleration of gravity.
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

None of the units make sense here, please recheck units and ask again
Acceleration of the object.
10 feet per second squared
Acceleration is the rate of change of velocity - how fast a velocity changes. Therefore, its units are naturally (meters/second) / second, usually written as meters/second2.Acceleration is the rate of change of velocity - how fast a velocity changes.

It is the rate of change of velocity. If the velocity changes from five to six meters per second in one second, then the acceleration is one meter per second per second.
The acceleration of the body is 3 m/s²
