The angle of pendulum from straight down will vary in a sinusoidal fashion as it swings. In Physics you will learn (if you haven't already) that for a frictionless pendulum, released k radians from feet vertical will be 0 (t) = k cos (t). g is gravitational acceleration, on Earth's surface~32 s2 %3D For our problem the length is 20 inches, which will require conversion to be the L in the equation. We will use k = 0.15 radians.
