A block sitting on a frictionless surface is attached to a spring of spring constant k. The other end of the spring is attached to the wall. The equilibrium length of the spring is x1. The spring is first compressed to a distance of x2, then released and extended to a length of x3. The elastic potential energy stored in the spring when it is extended to x3 can be calculated as: х, wwWO wwWO A block oscillating on the end of a spring Pick the correct answer PE = }ka?

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/s
