descending a 10% grade at a speed of 75 mi/h, David notices a large object in the roadway ahead of Q3. him. Without thinking about any alternatives, David stabs his brakes and begins to slow down with deceleration of 12 ft/s2. Calculate the minimum distance at which George must have seen the object in order to avoid crashing with it. You can assume that the roadway surface is concrete and that the surface is wet. You can also assume that David has a brake reaction time of 1.1 seconds because he is always alert on this stretch of the road
