Question

A particle of mass 0.1 kg oscillates with angular frequency 10 rad/s and amplitude 5 cm. Total energy is:
  1. A
    0.0125 J
    Correct
  2. B
    1.25 J
  3. C
    0.125 J
  4. D
    12.5 J

Correct answer

0.0125 J

Explanation

E = ½mω²A² = ½ × 0.1 × 100 × (0.05)² = ½ × 0.1 × 100 × 0.0025 = 0.0125 J.
