A uniform rod of mass M = 1.2 kg and length L = 0.80 m, lying on a frictionless horizontal plane, is free to pivot about a vertical axis through one end, as shown. The rotational inertia of the rod about this axis is given by (1/3)ML². If a force (F = 5.0 N, θ = 40°) acts as shown, what is the resulting angular acceleration about the pivot point? A)16 rad/s² B)12 rad/s² C)14 rad/s² D)10 rad/s² E)33 rad/s²
