A simple pendulum is suspended from the ceiling by means of a string of length 1.02 m. Assume that there is no friction or air resistance. Suppose you were to release the pendulum from rest, starting from an angle of 38.6 degrees with respect to the vertical, as shown. 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)?   Question 1 options:   3.95 m/s   4.47 m/s   0.63 m/s   2.09 m/s
