Ok so I have this problem and it seems pretty simple but Im not getting what its trying to say. According to Car and Driver, an Alfa Romeo going 70 mph requires 177 feet to stop. Assuming that the stopping distance is proportional to the square of the velocity, find the stopping distance required by an Alfa Romeo going at 35 mph and at 125 mph. How do you set this up, do I have to find an equation of a parabola whith the point (70, 177) and then find the others using it? The way its worded im not sure can any one confirm this or clerify it better for me?
