An instantaneous displacement of a simple harmonic oscillator is x = A ( t + / 4) . Its speed will be maximum at time

Options

  1. A/ 4
  2. B/ 2
  3. C/
  4. D2

Correct answer

A. / 4

Step-by-step solution

Velocity, v = dx dt =- A ( t + / 4) Velocity will be maximum, when t+ / 4= / 2 or t= / 2- / 4= / 4 or t= / 4
