While a person is walking, his arms swing through approximately a 45° angle in .530s. As a reasonable approximation, we can assume that the arm moves with constant speed during each swing. A typical arm is 70.0 cm long, measured from the shoulder joint. (a) What is the acceleration of a .800 gram drop of blood in the fingertips at the bottom of the swing?

1.54m/s^s i got correct

(b) Find the force that the blood vessel must exert on the drop of blood in part a.

im having touble solving this problem and part c

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

i know the formula i use is F=ma
