We have, v = u + at. Hence, we can write t = (v-u)/a Also, we know that, Distance = average velocity × Time Therefore, for constant acceleration we can write: Average velocity = (final velocity + initial velocty)/2 = (v+u)/2 Hence, Distance (s) = [(v+u)/2] × [(v-u)/a] or s = (v² – u²)/2a or 2as = v² – u² or v² = u² + 2as
