$\mathrm{}$ A simple pendulum is suspended from the ceiling by means of a string of length $1\mathrm{.}03$ m$.$ Assume that there is no friction or air resistance. Suppose you were to release the pendulum from rest, starting from an angle of $55\mathrm{.}6$ degrees with respect to the vertical. What will be the speed of the pendulum at the instant it swings through its lowest point $($that is$,$ when it s momentarily hanging vertically$)?$
