14.55. Model: Assume that the angle with the vertical that the pendulum makes is small enough so that there is simple harmonic motion. Solve: The angle θ made by the string with the vertical as a function of time is ( ) ( ) max 0 cos tt θω φ =+ The pendulum starts from maximum displacement, thus 0 0. = Thus, ( ) max cos . = To find the time t when the pendulum reaches 4.0 ° on the opposite side: () ( ) ( ) 1 4.0 8.0 cos cos
