A Uniform Rod of Mass M = 1

Multiple Choice

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
