Draw free body diagram and coordinate system Provide steps
The human heart is a powerful and extremely reliable pump. Each day it takes in and
discharges about 7,500 L of blood. Assume that the work done by the heart
corresponds to the height of that of the average American woman (1.63 m). In other
words, the heart needs to pump blood through her whole height. The density (mass per
unit volume) of blood is 1.05 x 103 kg/m³.
