Your friend is on rollerblades holding a pendulum. You gently push her forward and let go. You observe that the pendulum first swings in the opposite direction (backward) and then returns to the vertical orientation as she coasts forward. The angle the pendulum bob makes with the vertical is θ. Determine the acceleration of your friend while you are pushing her. Let m and g denote the mass of your friend and the free-fall acceleration, respectively. Express your answer in terms of some or all of the variables θ, m, and g.
