- 3) OK, once again we have a pendulum, this time of length 1.94 m, which you release from rest at an angle of 59.1 degrees to the vertical. What will be the speed of the pendulum at the instant it reaches an angle of 29.6 degrees above the vertical? Question 2 options: 6.88 m/s 3.68 m/s 4.30 m/s 2.23 m/s 4) This, the length of the pendulum is 2.17 m. Now you start with the pendulum at 10.2 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 34.0 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it? 2.70 m/s 0.82 m/s 3.51 m/s 2.57 m/s3. A simple pendulum is suspended from the ceiling by means of a string of length 1.60 m. Now you start with the pendulum at 16.6 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 55.4 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it? 4.78 m/s 3.50 m/s 3.68 m/s 1.14 m/sA pendulum oscillates is started with an amplitude of 00 = 5.0°.
