A uniform rod is set up so that it can rotate about a perpendicular axis at one of its ends. The length and mass of the rod are 0.849 m and 1.17 kg. What constant-magnitude force acting at the other end of the rod perpendicularly both to the rod and to the axis will accelerate the rod from rest to an angular speed of 6.67 rad/s in 9.47 s?

  1. force*radiusroataion=MomentInertia*alpha

    then wf=alpha*time

    force=MomentuInertia/radisuroatsion * wf/time
