A boat is subject to hydrodynamic drag forces of F = 40v^2[N] where v is the magnitude of velocity in [m/s]. The boat's mass is 450 kg and it is moving at 10 m/s when the engine is shut down. When the boat's velocity has decreased to 1 m/s, what distance has it moved from since the engine was shut down?
