Question

While a person is walking, his arms swing through approximately a 45.0? angle in 0.580s . As a reasonable approximation, we can assume that the arm moves with constant speed during each swing. A typical arm is 70.0cm long, measured from the shoulder joint.

Part A:

What is the acceleration of a 2.00 gram drop of blood in the fingertips 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:
