The hoop is cast on the rough surface such that it has an angular velocity ω = 5 rad/s and an angular acceleration α = 5 rad/s2 . Also, its center has a velocity vO = 3 m/s and a deceleration aO = 5 m/s2 .(Figure 1). Determine the acceleration of point A at this instant. Enter the x and y components of the acceleration separated by a comma.
