An object is formed by attaching a uniform, thin rod with a mass of mᵣ= 7.39 kg and length L = 4.84 m to a uniform sphere with mass mₛ= 36.95 kg and radius R = 1.21 m. Note mₛ= 5mr and L = 4R.
If the object is fixed at the left end of the rod, what is the angular acceleration if a force F = 424 N is exerted perpendicular to the rod at the center of the rod?
