A.) Suppose you have left Base Camp and are halfway to Station One. You have been accelerating to the east the entire trip, but you now realize you have forgotten your gloves. You immediately flip the fan control switch to backward, reversing the direction of the thrust.

System: The boat and its contents will be treated as a point particle with an external force from the action of the fan (actually from the air that the fan is pushing).
Model: One-Dimensional Motion With Constant Acceleration
B.) Sketch rough graphs of your position and velocity as a function of time from the instant the fan was reversed.
