Not enough information. You also need to know:* The initial speed
* How long it takes to speed up
If you divide the difference in speed by the time it takes to speed up, you get the average acceleration for that time period.
The acceleration is
(8 minus the speed when it began accelerating) / (time spent accelerating)
in the direction it moved during that time.
The basic formula for acceleration is the one that defines acceleration, as the rate of change of speed: a = dv/dt. For the case of constant acceleration, this is simply (change of velocity) / time. The unit is any unit of speed by a unit of time; in the SI that would be (meters / second) / second, usually written as meters / second squared.
10 meters/second2 refers to an acceleration. It is the same as 10 (meters/second) / second, and means that every second, the speed changes by 10 meters/second.
Assuming (1) the object starts from rest, (2) air resistance is insignificant, the object speeds up by about 9.8 meters/second every second. That's the strength of the gravitational field. Just multiply this acceleration (9.8 meters/second2) by the time.
There is no "unit for constant speed".The SI unit for speed (just "speed") is meters per second. Constant speed means there is no acceleration; the unit for acceleration is meters per second squared.
Ignoring air resistance, its horizontal speed is still 9 meters per second, its vertical speed is approx. 9.81 m/s, as the acceleration of gravity is 9.81 meters per second per second.
Acceleration is not measured in meters/second. Meters/second is a unit of speed. Since acceleration is defined as change of speed divided by time, the units are meters/second/second, usually written as meters/second2.
Acceleration is the increase in speed from one unit of time to the next, so the described object has no acceleration. Its speed is constant.
"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.

Speed or acceleration
Average acceleration = change in speed/time for the change = 15/5 = 3 meters per second2 .
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
1.667 metres per second squared
Kilometers per hour is used to measure speed, not acceleration. In SI, the acceleration is commonly measured in meters per square second.Kilometers per hour is used to measure speed, not acceleration. In SI, the acceleration is commonly measured in meters per square second.Kilometers per hour is used to measure speed, not acceleration. In SI, the acceleration is commonly measured in meters per square second.Kilometers per hour is used to measure speed, not acceleration. In SI, the acceleration is commonly measured in meters per square second.
Acceleration = (change in speed)/(time for the change) = (15-5)/(6) = 10/6 = 12/3 meters per second2

It is about 9.814 meters per second per second on Earth
Assuming you want the international units: time: second velocity: meters / second distance: meters acceleration: meters / second2
