Respuesta :
The total momentum of the system is 81.69 kg m/s.
Define momentum.
The result of a particle's mass and velocity is momentum. It has both magnitude and direction because momentum is a vector quantity. According to Isaac Newton's second law of motion, the force pushing a particle has an equal and opposite effect on the temporal rate at which its momentum changes. According to Newton's second law, if a particle is subjected to a constant force for a specific amount of time, the impulse, which is the product of the force and the time interval, is equal to the change in momentum. In contrast, a particle's momentum is a measurement of the amount of time needed for a consistent force to bring the particle to rest.
According to the question:
Total momentum = Momentum of Christine's car + Momentum of Demon's car.
Total momentum = (37.8+43.89) kg m/s.
= 81.69 kg m/s.
