Question

The maximum velocity and maximum acceleration of a body moving in a simple harmonic motion are 2m/s and 4m/s^2 respectively. What will be the angular velocity?

(a) 4 rad/sec

(b) 3 rad/sec

(c) 2 rad/sec

(d) 8 rad/sec

I have been asked this question by my college director while I was bunking the class.

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

Answer 1

Correct choice is (c) 2 rad/sec

Easy explanation: vmax=ωA, amax=ω^2 A

ω=amax/vmax = 4/2

ω=2rad/sec.
