It's really complicated. total stopping distance is the sum of the perception-reaction distance and the braking distance. D_{total}=D_{p-r}+D_{braking}=v t_{p-r}+ \frac{v^2}{2 \mu g}. A common baseline value of t_{p-r}=1.5 s, \mu=0.7 is used in stopping distance charts.
Hematology is the study of blood in health and disease. It includes problems with the red blood cells, white blood cells, platelets, blood vessels, bone marrow, lymph nodes, spleen, and the proteins involved in bleeding and clotting (hemostasis and thrombosis).hen something is wrong with your blood, it can affect your total health.

Hematology is the branch of medical practice concerned with conditions of the blood. These conditions range from benign problems such as anemia or coagulation disorders, to the malignant conditions of blood and lymphatic organs such as leukemia or lymphoma. A decrease in the red blood cells and, therefore, the hemoglobin concentration of the blood. This results in a decreased capacity of the blood to carry oxygen. a type of anemia caused by low or absent iron stores. Iron deficiency anemia is the most common form of anemia. Iron is an essential component of hemoglobin, the oxygen-carrying pigment in the blood. Iron is normally obtained through the food in the diet and by the recycling of iron from old red blood cells.
