Question

In the nth second, a body starting from rest covers a distance of (2n − 1) units. The acceleration is:
  1. A
    1 unit/s²
  2. B
    2 unit/s²
    Correct
  3. C
    3 unit/s²
  4. D
    0.5 unit/s²

Correct answer

2 unit/s²

Explanation

Distance in nth second: sₙ = u + a(2n−1)/2 = 0 + a(2n−1)/2. Given sₙ = 2n−1: a/2 = 1 → a = 2 unit/s².
