SUMMARY
The velocity of a ball when it hits the ground can be calculated using the equation v^2 = v_i^2 + 2gh_b, where v_i is the initial velocity, g is the acceleration due to gravity, and h_b is the height above the ground. The user attempted to solve for the final velocity using an incorrect formula, v_2 = v_i^2 + sqrt(2gh_b), which does not yield the correct results. The correct approach involves substituting the initial conditions into the established equation to derive the final velocity accurately.
