Question

x = 5 sin(3πt + π/6) cm. Amplitude, frequency, and initial phase are:
  1. A
    5 cm, 3π Hz, π/6
  2. B
    5 cm, 3/2 Hz, π/6
  3. C
    5 cm, 1.5 Hz, π/6
  4. D
    Both B and C
    Correct

Correct answer

Both B and C

Explanation

A = 5 cm. ω = 3π rad/s → f = ω/(2π) = 3π/(2π) = 1.5 Hz. Initial phase φ = π/6.
