Acceleration is measured in distance per unit timer per unit time, or in SI units this is usually m/s/s or m/s^2. If an object's velocity increases by 15 m/s in five seconds this is an average acceleration of:
15 m/s / 5 s = 3 m/s/s
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
Average acceleration = change in speed/time for the change = 15/5 = 3 meters per second2 .
-2.33 metres per second squared
If he started out from "rest" (zero speed), then his average acceleration for the 5 seconds is50/5 = 10 meters per second2
Average acceleration is the amount of acceleration per unit of time that a thing or an object undergoes. It is simple to discover. To find the average acceleration, we need only find out how much acceleration occurred and over what period of time. If we have the starting and the ending speeds, then by subtracting them we can find the chane of acceleration. Then we can divide that acceleration by the time it took to occur. The eagle in our example accelerates from 15 m/s to 22 m/s over a period of 4 seconds. His total acceleration was 7 m/s (22 m/s minus 15 m/s = 7 m/s), and, since it took 4 seconds to increase his speed by 7 m/s, the average acceleration is the total acceleration divided by the time it took to happen (as was stated). The average acceleration is 7 m/s divided by 4 seconds or 1.75 meters per second.
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
Average acceleration = change in speed/time for the change = 15/5 = 3 meters per second2 .
Average acceleration = (change in speed) divided by (time for the change)= (80) / (20) = 4 meters per second2

If you divide the meters by the seconds, you get the average speed. But that would be in meters / second, not in meters per second squared, which is a unit of acceleration.
Not sure of your abbreviations. I'll assume that 'ms' = "meters per second", and 's' = "seconds" Change in speed = (25 - 0) = 25 meters per second Time = 8 seconds Average acceleration = (change in speed) / (time) = 25/8 = 3.125 meters per second2
Average acceleration = (change in speed) divided by (time for the change) =(15 - 0) / (5) = 15/5 =3 meters per second2
Average acceleration = (change in speed) divided by (time interval)A = (40 - 25) / 15 = 15/15 = 1 meter/sec2
