$8.$ Consider three pendulums. The pendulum arms are all the same length. The masses attached to the pendulums are m$1=1$ kg$,$ m$2=$ m$3=0\mathrm{.}5$ kg$,$ and their maximum angular displacements are $1=$ $2=0\mathrm{.}4$ rad and $3=0\mathrm{.}2$ rad. Rank the speeds of these three pendulums as they pass through their equilibrium position. A$.$ v$2=$ v$3<$ v$1$ B$.$ v$3<$ v$1<$ v$2$ C$.$ v$3<$ v$1=$ v$2$ D$.$ v$1=$ v$3<$ v$2$ E$.$ v$3<$ v$2<$ v$1$
