उत्तर
According to newton's second law of motion, when a force acts on a body, the rate of change in momentum of a body is equal to the product of the mass of the body and acceleration produced in it.
Yes, Newton's first law is contained in the second law as if force is zero then the acceleration would be zero which means the body would remain in its state of rest or in state of constant motion.
