17. A space probe has two engines. Each generates the same amount of force when fired, and the directions of these forces can be indepen- dently adjusted. When the engines are fired simultaneously and each ap- plies its force in the same direction, the probe, starting from rest, takes 28 s to travel a certain distance. How long does it take to travel the same distance, again starting from rest, if the engines are fired simultaneously and the forces that they apply to the probe are perpendicular?
