Which one of the following equations of motion represents simple harmonic motion?

Options

  1. AAcceleration =- k ₀ x + k ₁ x ^2
  2. BAcceleration =- k ( x + a )
  3. CAcceleration = k ( x + a )
  4. DAcceleration = kx where k ₁ k ₀, k ₁ and are all positive.

Correct answer

B. Acceleration =- k ( x + a )

Step-by-step solution

Key Idea Acceleration - (displacement). aligned & A -y & A=- ^2 y & A=- k m y & A=-k y aligned Here, y=x+a acceleration =- k ( x + a )
