This information can be obtained by means of a ballistocardiograph. The instrument works as follows: The subject lies on a horizontal pallet floating on a film of air. Friction on the pallet is negligible. Initially, the momentum of the system is zero. When the heart beats, it expels a mass m of blood into the aorta with speed v, and the body and platform move in the opposite direction with speed V. The speed of the blood tan be determined independently (e.g., by observing an ultrasound Doppler shift). Assume that the bloods speed is 50.0 cm/s in one typical trial. The mass of the subject plus the pallet is 54.0 kg. The pallet moves at a speed of 6.00 105 m in 0.160 s after one heartbeat. Calculate the mass of blood that leaves the heart. Assume that the mass of blood is negligible compared with the total mass of the person. This simplified example illustrates the principle of ballistocardiography, but in practice a more sophisticated model of heart function is used.

- Under what circumstances is momentum conserved?Review. There are (one can say) three coequal theories of motion for a single particle: Newtons second law, stating that the total force on the particle causes its acceleration; the workkinetic energy theorem, stating that the total work on the particle causes its change in kinetic energy; and the impulsemomentum theorem, stating that the total impulse on the panicle causes its change in momentum. In this problem, you compare predictions of the three theories in one particular case. A 3.00-kg object has velocity 7.00jm/s. Then, a constant net force 12.0iN acts on the object for 5.00 s. (a) Calculate the objects final velocity, using the impulsemomentum theorem. (b) Calculate its acceleration from a=(vfvi)/t. (c) Calculate its acceleration from a=F/m.
