Final answer:
The equation that can be used to model simple harmonic motion is d = asin(wt)+k (Option A).
Step-by-step explanation:
The equation that can be used to model simple harmonic motion is d = asin(wt)+k (Option A).
This equation represents a sinusoidal wave with an angular frequency w. In this equation, d represents the displacement, a represents the amplitude, wt represents the angular velocity, and k represents the phase constant.
For example, if you have a mass on a spring undergoing simple harmonic motion, the displacement of the mass at any given time can be represented by this equation.
