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.
