WebApr 22, 2024 · The coefficient of determination is a number between 0 and 1 that measures how well a statistical model predicts an outcome. The model does not predict the … WebFinal velocity (v) squared equals initial velocity (u) squared plus two times acceleration (a) times displacement (s). v 2 = u 2 + 2 a s. Solving for v, final velocity (v) equals the square root of initial velocity (u) squared plus two times acceleration (a) times displacement (s). v = u 2 + 2 a s. Where: v = final velocity. u = initial velocity.
