The length of a simple pendulum is 0.72 m, the pendulum bob has a mass of 295 g, and it is released at an angle of 12° to the vertical. Assume SHM.
(a) With what frequency does it oscillate?
(b) What is the pendulum bob's speed when it passes through the lowest point of the swing?
(c) What is the total energy stored in this oscillation assum- ing no losses?
To transmit only portions of an input wave lying on one side of an amplitude boundary, you would use a.
