While a person is walking, his arms (with typical lengths 70 measured from the shoulder joint) swing through approximately a 45 angle in 0.5 . As a reasonable approximation, we can assume that the arm moves with constant speed during each swing.
B. Draw a free-body diagram for the drop of blood in part A.
C.Find the magnitude of the force that the blood vessel must exert on the drop of blood.
D.What force would the blood vessel exert if the arm were not swinging?
