A pendulum is a weight attached to a fixed rod, as shown in the figures. Suppose that during an experiment, a pendulum moves back and forth in a periodic manner. At the beginning of the experiment, when the time is t=0 seconds, the pendulum is at a point halfway between its maximum and minimum distances from the wall, 3 m away from the wall (Figure 1) and moving away from the wall. The pendulum first reaches its maximum distance from the wall, 5 m from the wall, when t = 2 seconds (Figure 2). When t = 8 seconds, the pendulum is back to a point halfway between its maximum and minimum distances from the wall. The pendulum continues to move back and forth so that the distance between the pendulum and the wall over time can be modeled by a sinusoidal function. Let f(t) be the distance between the wall and the pendulum t seconds after the beginning of the experiment.

during an experiment, a pendulum moves back and forth in a periodic manner. At the
beginning of the experiment, when the time is t=0 seconds, the pendulum is at a point
halfway between its maximum and minimum distances from the wall, 3 m away from
the wall (Figure 1) and moving away from the wall. The pendulum first reaches its
maximum distance from the wall, 5 m from the wall, when t=2 seconds (Figure 2).
When t = 8 seconds, the pendulum is back to a point halfway between its maximum and
minimum distances from the wall. The pendulum continues to move back and forth so
that the distance between the pendulum and the wall over time can be modeled by a
sinusoidal function.
Let f(t) be the distance between the wall and the pendulum t seconds after the
