A 23-cm-long pen is tossed up in the air, reaching a maximum height of 1.7 mabove its release point. On the way up, the pen makes 2 revolutions. Treatingthe pen as a thin uniform rod, calculate the ratio between the rotational kineticenergy and the translational kinetic energy at the instant the pen is released.Assume that the rotational speed does not change during the toss.The moment of inertia of the rod with axis through the center of mass isdetermined by ImL² where m is its mass and L is its length.
