Question

A particle executes simple harmonic motion with an angular velocity of 3.5 rad/sec and maximum velocity acceleration 7.5 m/s^2 respectively. What is the amplitude of oscillations?

(a) 0.28m

(b) 0.36m

(c) 0.707m

(d) Zero

This question was addressed to me in an interview.

The question is from Oscillatory Motion in chapter Oscillations of Engineering Physics I

Answer 1

The correct choice is (d) Zero

The best I can explain: amax=ω^2 A

A=amax/ω^2 = 7.5/(3.5×3.5)=0.61m.
