Physics of Sound

  1. A particle executing S.H.M. has amplitude 0.01m and frequency 60 Hz. The maximum acceleration of the particle is​​
    1. 144 π2 m/s2
    2. 120 π2 m/s2
    3. 80 π2 m/s2
    4. 60 π2 m/s2
Correct Option: A

Amplitude (A) = 0.01 m, Frequency = 60 Hz ​
Maximum acceleration = A ω2 = 0.01 × (2πn)2
= 0.01 × 4π2 × 60 × 60 = 144 π2 m / sec2
