Approach: Once the fan has been reversed, the acceleration is in the opposite direction from the velocity. Taking the velocity at fan-reversal to be the initial velocity, the Thus, the boat will immediately begin to slow down. As it slows, it will continue to move east, however. In the language of our one-dimensional system, the velocity immediately begins to decrease with time, but the position continues to increase.
B.) Sketch rough graphs of your position and velocity as a function of time from the instant the fan was reversed.
