Pendulum released from rest at angle \(\theta_0\).
Pendulum released from rest at angle \(\theta_0\).
A simple pendulum consists of a small bob of mass \(m\) attached to an ideal string of length \(L\). The bob is pulled to an angle \(\theta_0\) from the vertical and released from rest at time \(t = 0\), undergoing simple harmonic motion in a vertical plane. Which of the following free-body diagrams best represents the forces acting on the bob at the instant it is released?
