Question

Which equation can be used to model simple harmonic motion

Answer 1

Answer:x(t)= Acos(wt)

Explanation:

According to Newton's 2nd law,a particle of mass m acted on by a force is given by:Fs=-kx

Where x is displacement from equilibrium

K = spring constant

Therefore X(t) = Acos(2pit/T)

X(t)= Acos(wt)

Answer 2

d= asin(wt). it was the simplest answer and thats how i choose to remember it
