While a person is walking, his arms swing through approximately a 45.0 degree angle in 1/2 s. As a reasonable approximation, we can assume that the arm moves with a constant speed during each swing. A typical arm is 70.0 cm long, measured from the shoulder joint.
part a:
What is the acceleration of a 1.00 gram drop of blood in the finger tips at the bottom of the swing?
part b:
Find the force that the blood vessel must exert on the drop of blood in part (a)
part c:
What force would the blood vessel exert if the arm were not swinging?
