Answer:

Step-by-step explanation:
The formula is given as:

We need to solve this formula for v, that means that v to one side and let it be solved in terms of the other variables (E and m). First, we isolate v:

To isolate v, and eliminate the "square", we need to take square roots of both sides, that will give us v in terms of the other variables:

Putting v to left side (convention), we finally have:
