According to a simplified model of a mammalian heart, at each pulse approximately 20 g of blood is accelerated from 0.21 m/s to 0.36 m/s during a period of 0.11 s . What is the magnitude of the force exerted by the heart muscle?
Homework Answers
Here, acceleration = (0.36 - 0.21)/0.11
= 1.363 m/sec2
=> magnitude of the force exerted by the heart muscle = 0.02 * 1.363
= 0.02726 N

Problem: (2 Parts) Below we show a simplified model of a person's leg in cast that is pulled up by a sling. The leg and cast together is the system that is modeled as a rigid beam of mass m = 28.0 kg and length L = 0.80 m that is attached to the body at a hinge at point A. The leg and cast are lifted by the sling that exerts a vertical force of magnitude, F which is...

In the human body, the aorta is the major artery that conducts blood from the heart to the rest of the body. The abdominal aorta is a relatively long straight section of the aorta that runs down from the chest to the pelvis. This section is prone to aneurisms, where a section of the aorta fails and stretches. In order to study how wall shear from blood flow in this portion of the aorta may contribute to aneurisms, a laboratory...

While a person is walking, his arms swing through approximately a 45.0 ∘ angle in 0.480 s . As a reasonable approximation, we can assume that the arm moves with constant speed during each swing. A typical arm is 70.0 cm long, measured from the shoulder joint. 1.What is the acceleration (m/s^2) of a 1.70 gram drop of blood in the fingertips at the bottom of the swing? 2. Find the force (N) that the blood vessel must exert on...

A model rocket is fired vertically from rest. It has a net acceleration of 15.6 m/s^2. After 1.25 s, its fuel is exhausted and its only acceleration is that due to gravity. The model rocket has a mass of 92.4 g and you may assume the mass of the fuel is much less than 92.4 g. What was the net force on the rocket during...
