A 23-cm-long pen is tossed up in the air, reaching a maximum height of 1.7 m above its release point. On the way up, the pen makes 2 revolutions. Treating the pen as a thin uniform rod, calculate the ratio between the rotational kinetic energy 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 is determined by ImL² where m is its mass and L is its length.
