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:
