acceleration = change in velocity divided by time
accel = (9-3)/3 = 6/3 = 2 meters per second per second
Because if speed is measured in meters per second (m/s) and time is measured in seconds, the SI unit of acceleration is meters per second per second (m/s2). ^_^
The sprinter's acceleration is 2 meters per second squared.
-2.33 metres per second squared
In general, the acceleration during that time interval could vary considerably. However, we can calculate the average acceleration during the interval. The change in speed is 20 meters per second - 5 meters per second = 15 meters per second, and this change in speed occurs over a 3 second interval. Thus the average change in speed over this interval is 15 meters per second/ 3 seconds = 5 meters per second per second = 5 meters/second2
Acceleration = (change in speed) divided by (time for the change) = (25) / (10) = 2.5 meters per second2
"470 meters per second" is a speed, not an acceleration. Assuming you mean "470 meters per second square", that is the same as a change of 470 meters per second every second. Just multiply by the number of seconds to get the change in speed."470 meters per second" is a speed, not an acceleration.

Acceleration = (change in speed) divided by (time for the change)Acceleration = (96 - 32) / 8 = 64/8 = 8 meters per second2
1.667 metres per second squared
Acceleration = (change in speed) divided by (time for the change) = (25) / (10) = 2.5 meters per second2
The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.
The speed of the plane after 10 seconds of acceleration at 15 m/sĀ² would be 150 meters per second. This is calculated by multiplying the acceleration (15 m/sĀ²) by the time (10 seconds).
(10 - 30)/4 = -5.0 meters per second per second (which can be written also as meters per second squared).
The speed of an object after falling for 3 seconds, ignoring air resistance, would be approximately 29.4 m/s. This value is derived from the acceleration due to gravity (9.8 m/s^2) multiplied by the time the object has been falling (3 seconds).
