The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Answer:
Force of 540 Kgm/s^2 is closest to the net force acting on the vehicle.
Explanation:
Force is the change in momentum per unit time
This relationship is equivalent to product of mass and acceleration
Thus F = Mass * acceleration
Substituting the given values in above equation we get -
F = 450 Kg * 1.2 m/s^2
F = 540 Kgm/s^2
