Question
A train travels with an initial velocity of 20 m/s. If it accelerates uniformly at 2 m/s² and travels 100 m, calculate the final velocity.
Correct Answer
Option C is the correct answer.
Detailed Explanation
Using v² = u² + 2as: v² = 20² + 2×2×100 = 400 + 400 = 800. v = √800 = 28.28 m/s ≈ 28.3 m/s.
Hint
v² = u² + 2as.
