A 3-in.-radius drums rigidly attached to a 5-in.-radius drum as shown. One of the drums rolls without sliding on the surface shown, and a cord is wound around the other drum. Knowing that at the instant shown, point A has a velocity of 5.250 in./s and an acceleration of 17.00 in./$s^2$, both directed to the right, determine the accelerations of points A, B, and C of the drums.
The accelerations of point B is $\boxed{}$ in./$s^2$.
The accelerations of point A is $\boxed{}$ in./$s^2$.
The accelerations of point C is $\boxed{}$ in./$s^2$.
