(II) According to a simplified model of a mammalian heart, at each pulse approximately 20 $g$ of blood is accelerated from 0.25 m/s to 0.35 m/s during a period of 0.10 s. What is the magnitude of the force exerted by the heart muscle?

I know you have a question and this. It is given there Approximately 20. Our blood accelerates from 0.25 m purse again to 0.35 m purse again for 10 seconds. So we have to find a force. The force is always equal to mass into exploration. Some masks into the tu minus we even by teeth, So masses 20 times 25 1000 kg into veto is 0.35 meter purse. Again minus zero point. You will find meter per second And divided by time is 0.10 2nd. So this is 25 1000 everything in essay. So let us just leave the unit 0.10 x 0.10. Okay, this Juliet can float. So trolls will be equal to 0.02 newton's. They should be the answer. Thank you.
