Answer:
Approximately .
Explanation:
Consider one of the equations for constant acceleration ("SUVAT" equations)
,
where
Note that unlike other SUVAT equations, this one does not ask for the time required for the speed of the object to change from to . Since in this problem, time isn't given, this time-less equation would particular useful.
Here
Rearrange the equation to isolate the unknown, :
.
Make sure that all units are standard, so that the unit of the output will also be standard. Apply the equation:
.
Hence the final velocity will be approximately .

4. a prediction
Explanation:
According to the scientific method, an experiment is conducted to test a prediction/hypothesis stemming from the previous question.
A conclusion ... usually called a "theory" ... is tested. (3)
One great way to test a conclusion is to follow up on its predictions, and see how they turn out.
