Aldrin notices a large object in the roadway ahead of him while dropping a grade of -5 percent at a speed of 80 km / h. Aldrin stabs his brakes and begins to slow down without thinking about any alternatives. Assuming Aldrin is so paralyzed with fear that he will not engage in an avoidance maneuver, to avoid colliding with it, calculate the minimum distance at which Aldrin must have seen the object. You can assume the surface of the roadway is concrete and the surface is wet. You can also assume that Aldrin has a brake response time of 1.0 seconds because, on this stretch of the road, he is always alert.
