During a cardiac cycle, the heart squeezes about 65g of blood on each contraction into the arterial circulation. The center of mass of this blood moves about 7cm. During a "diastole," the heart refills with blood entering from the vena cava and pulmonary veins. We approximate the motion of the center of mass of the blood with a harmonic motion.
A) the heart rate is 75 bpm [beats per minute]. Find the angular frequency of the oscillation.
B) what is the maximum force acting on the center of mass of the blood?
