A uniform rod of mass $2.0\ \text{kg}$ and length $1.0\ \text{m}$ is hinged at one end to a wall, so that it can turn freely in a vertical plane. It is held horizontal and then released, as shown in the figure. Take $g = 10\ \text{m/s}^2$. Which of the following statements are correct?

Fig. 1: A uniform rod of length L = 1.0 m and mass 2.0 kg is hinged at its left end to a wall and held horizontal. A dashed copy shows the rod later hanging straight down from the hinge, with a curved dashed arrow from the horizontal position to the hanging one.
