This, the length of the pendulum is 1.66 m. Now you start with the pendulum at 17.1 degrees with respect to the vertical, but rather than releasing it from rest, you give it a push downward. It swings to the other side, and reaches a maximum angle of 42.7 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it? 2.68 m/s 2.94 m/s 1.20 m/s 3.53 m/s
