1. The problem statement, all variables and given/known data
we know that the simple armonic motion is characterized by x(t)=Acos(wt), find velocity and acceleration of s.h.m. using derivatives.

2. Relevant equations

3. The attempt at a solution
i should find derivatives of the component of the vector R (Rcos(wt),Rsin(wt)).

first derivative is velocity, second derivative is acceleration

I don't see why you would change this into a 2D problem. It is phrased as a 1D problem where x is position. Velocity should just be $\frac{d}{dt} x(t)$
