Question

6. A uniform rod of mass M = 1.1 kg and length L = 0.8 m, lying on a frictionless horizontal plane, is free to pivot about a vertical axis through one end, as shown. The moment of inertia of the rod about this axis is given by 1/3 ML². If a force (F = 6 N, ? = 60°) acts as shown, what is the resulting angular acceleration about the pivot point? a. 24 rad/s² b. 18 rad/s² c. 26 rad/s² d. 20 rad/s² e. 22 rad/s² 7. A uniform rod (L = 2 m) is mounted to rotate freely about a horizontal axis that is perpendicular to the rod and that passes through the rod at a point 0.25 m from one end of the rod. If the rod is released from rest in a horizontal position, what is the angular speed of the rod as it rotates through its lowest position? a. 4.1 rad/s b. 4.6 rad/s c. 1.3 rad/s d. 1.5 rad/s
