A pendulum consists of a mass hanging at the end of a string which is 18 cm long. Find the vertical height through which the mass rises and falls as the pendulum swings through 30° on each side of the vertical.
-----------------------------
Sketch a right triangle with the hypotenuse = 18 cms and the angle at the pivot = 30 degs.
==================
PS Pendulums used for timing do not swing more than 8 degs from vertical.
