Determine how long the body is moving with acceleration 12 m / s² from the state of rest, cover the path of 1000m and find the final speed
We use the formula:
S = (v2 ^ 2 – v1 ^ 2) / 2a, where v1 and v2 are initial and final speeds, a is acceleration. In this case, v1 = 0.
v = √2 a * S.
v = √2 * 12 * 1000 = 156 m / s
