Question

The velocity of a particle (v) moving with simple harmonic motion, at any instant is given by

(a) ω √r^2 − x^2

(b) ω √x^2 − r^2

(c) ω^2 √r^2 − x^2

(d) ω^2√x^2 − r^2

This question was posed to me during an interview.

I need to ask this question from Simple Harmonic Motion in section Simple Harmonic Motion of Machine Kinematics

Answer 1

The correct answer is (a) ω √r^2 − x^2

Easy explanation: Velocity of any particle vN = vsinθ = ω.rsinθ = ω √r^2 − x^2.
