What do you mean "no"?  Mass on a spring ths the classic example from
ordinary differential equation courses and freshman physics.

The solution to y" + ky = 0 is A cos(wt) + B sin(wt)  where w = sqrt(k)
and A and B depend on initial conditions. For mass on a spring, y is the
position as a function of time, therefore y" is the acceleration from the
spring.

As I stated, all solutions of y" + ky = 0, k > 0 are sinusoidal,
regardless of whether rotation is involved.
