towards equilibrium. What are the block's
(1) oscillation frequency,
(2) distance from equilibrium when its speed is 50 cm/s,
(3) distance from equilibrium at t = 1.0s.

This, the length of the pendulum is 2.16 m. Now you start with the pendulum at 30.5 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 50.8 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it? 3.12 m/s 3.95 m/s 2.42 m/s 6.32 m/s

A spring is mounted vertically on the floor. The mass of the spring is negligible. A certain object is placed on the spring to compress it. When the object is pushed further down by just a bit and the released, one up/ down oscillation cycle occurs in 0.230s. However, when the object is pushed by 5.32 x 10-2 m from unstrained position to point P and then released, the object flies entirely off the spring. To what height above point P does the object rise in the absence of air resistance?

A spiral staircase wind up to the top of the tower in an old castle. To measure the height of the tower, a rope is attached to the top of the tower and hung down the center of the staircase. However, nothing is available with which to measure the length of the rope. Therefore, at the bottom of the rope a small object is attached so as to form a simple pendulum that just clears the floor. The period of the pendulum is measure to be 6.53 s. What is the height of the tower?
