Question

A spring-mass system (m = 0.5 kg, k = 200 N/m) is given initial amplitude 4 cm. Maximum acceleration is:
  1. A
    16 m/s²
    Correct
  2. B
    1.6 m/s²
  3. C
    160 m/s²
  4. D
    0.16 m/s²

Correct answer

16 m/s²

Explanation

ω = √(200/0.5) = 20 rad/s. a_max = ω²A = 400 × 0.04 = 16 m/s².
