Answer:
43.88 meters per second
Explanation:
The computation of the speed is shown below:
As we know that

where,
Distance is 395,000 meters
Time is 9,000 seconds
Now placing these values to the formula
So, the speed is

= 43.88 meters per second
As speed shows the relation between the distance and time and the same is to be considered i.e by applying the formula
Acceleration occurs whenever the forces on an object are unbalanced.
It's the group of forces on the object that's either balanced or unbalanced.
There's no such thing as "an unbalanced force".
