question

While a person is walking, his arms swing through approximately a 45° angle in 0.5s.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. What is the acceleration (in metre per second squared) of a 1.0 g drop of blood in the fingertips at the bottom of the swing?
