For small oscillations, the horizontal position of the mass at the end of an ideal pendulum (one for which there is no friction) can be described by the equation below: 32(23) = A sin(wt + ()5) Here, 33(13) is the position, 3:, of the mass, m, at time t; A, w and 95 are the amplitude, angular frequency and initial phase, respectively. Using A = 0.10 m,
