Question

A particle executing simple harmonic motion has amplitude 0.01 and frequency 60Hz. The maximum acceleration of the particle is ___________

(a) 144 π^2 m/s^2

(b) 80  π^2 m/s^2

(c) 120 π^2 m/s^2

(d) 60 π^2 m/s^2

This question was addressed to me by my school principal while I was bunking the class.

The question is from Wave Motion topic in section Waves of Engineering Physics I

Answer 1

Correct option is (a) 144 π^2 m/s^2

Best explanation: amax=ω^2 A=4π^2 v^2 A

=4π^2×60×60×0.01=144 π^2 m/s^2.
