4. In the figure shown, rod AB (M-2 kg, L-2 m, center of mass C located 1 m above ground) is kept on a rough surface (H-0.5). A horizontal force F = 10 N is applied to the rod at point D, and distance CD-L/3 m. This horizontal force F causes the rod to rotate about B. Find initial linear acceleration of the top-most point A of the rod. Figure inset shows moment of inertia of a rod. Ignore air...
