Practical stopping distance is something you may come across in class or in the real world. There are multiple engineering classes where this equation is needed. This equation is also useful in a real life. If you are trying to figure out how far you travel before you are stopped this equation is very useful.
So whether you are trying to solve an engineering problem or trying to avoid a deer in the middle of the road these instructions can be very helpful. Depending on how many givens you have given to you in the problem this process should only take at most 15 minutes. If you are trying to solve for your own car it will take you more time because you have to measure deceleration and grade.
