Answer: v² = u² + 2as.
- A v = u + at
- B s = ut + ½at²
- C v² = u² + 2as
- D s = (u+v)t/2
Correct answer: C. v² = u² + 2as
Explanation: v² = u² + 2as directly links velocity and displacement without requiring time.
On a velocity-time graph for uniform acceleration, the slope of the line gives the acceleration and the shaded area under the line gives the displacement.
