Michael Joseph, a Form 6 student in Seremban, recently studied the principles of work, power, and fluid pressure in his physics class. Intrigued by how he could apply this newfound knowledge, Michael wanted to calculate the power generated by the human heart as it propels blood throughout the body. Michael came across the following information about the typical human heart's pumping capacity and the pressure it exerts from a medical journal: Parameter Volume of blood pumped per heartbeat Pressure exerted by the heart Value 80 ml 15 cm of Mercury Assuming a pulse frequency of 82 beats per minute, Michael estimated the heart's power output to be 220 W. Do you agree with his answer? Justify your reasoning with calculation. State any assumptions made.
