We have the following expression: y = (v ^ 2) / (2 * a) We must clear v from the equation. For this, we follow the following steps: Step 1) Pass 2 * a to multiply: 2 * a * y = v ^ 2 Step 2) Square root on both sides: root (2 * a * y) = v Step 3) Rewrite expression: v = root (2 * a * y) Answer: v = root (2 * a * y) (option 1)
