$3.$ In Figure L$3-1$ is a simple pendulum with the mass of the bob is M$,$ the length of the pendulum is $\backslash ($ L $\backslash ).$ The motion of the system takes place in a vertical plane when the mass $\backslash (\backslash$boldsymbol$\{$M$\}\backslash )$ is released from an initial angle $\backslash (\backslash$boldsymbol$\{\backslash$theta$\}\backslash )$ with respect to the vertical. What is the component of the weight of $\backslash (\backslash$boldsymbol$\{$M$\}\backslash )$ that is directed along the arc $(\backslash (\backslash$boldsymbol$\{$F$\}\_\{\backslash$text $\{$arc $\}\}\backslash ))$ of the motion of $\backslash (\backslash$boldsymbol$\{$M$\}\backslash )?$ Label clearly and resolve the $\backslash (\backslash$boldsymbol$\{$x$\}\backslash )-\backslash (\backslash$boldsymbol$\{$y$\}\backslash )$ components in the Figure.
