Determine what force would the blood vessel exert

Reference no: EM13547460

While a person is walking, his arms (with typical lengths 70 cm measured from the shoulder joint) swing through approximately a 45 degree angle in 0.5 sec. As a reasonable approximation, we can assume that the arm moves with constant speed during each swing.

A) What is the acceleration of a 1.2 g drop of blood in the fingertips at the bottom of the 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) Find the direction of the force that the blood vessel must exert on the drop of blood.

E) What force would the blood vessel exert if the arm were not swinging?
