Question

at each pulse of a simplified model of a mammalian heart, about 40 grams of blood is accelerated from 0.35 meter per second to 0.45 meter per second during a period of 0.10 seconds. Calculate the magnitude of theforce exerted by the heart.

Answer 1

force=mass*changevelocy/time
change velocity/time=.10/.1 m/s^2 or 1 m/s^2

mass= .040kg
