What do we already know? We know the values for acceleration (a), velocity (v), distance (y), height (y_0) and want to calculate the value of velocity (v_0). According to the initial data we have about the problem, the following formula would be the most useful to find the unknown (v_0) that we are looking for. We need to solve the equation below for v_0. We substitute the data of the problem in the formula and proceed to simplify the equation. Multiply -2 times 9.81.
