The length of a simple pendulum is 0.67m, the pendulum bob has a mass of 295g, and it is released at an angle of 12 degrees to the vertical. Assume simple harmonic motion.
(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 assuming no losses?
