Q1
A particle moves in the xy-plane such that its x-coordinate is given by $$x(t) = R\cos(\omega t)$$ and its y-coordinate is given by $$y(t) = R\sin(\omega t)$$, where $$R$$ and $$\omega$$ are positive constants. Which statement correctly describes the magnitude of the particle's acceleration vector?
