I think it may help you,
According to Newton's second law:The rate of change of momentum of a body is directly proportional to the applied force.Suppose a body of mass m having an initial velocity u.Initial momentum=munow a force F acts on the body for time t,and final velocity becomes v.Final momentum=mvChange in momentum=mv-muNow according to Newton's law

Newton's second law says that an object with mass M subjected to force F, will accelerate in the direction of the force with acceleration A and the acceleration will be proportional to the force, inversely proportional to the mass:
A= F/M....... this leads to F=M*A

ACC TO NEWTONS SECOND LAW OF MOTION THE RATE OF CHANGE OF MOMENTUM IS DIRECTLY PROPORTIONAL TO THE APPLIED FORCE.
ACC TO NEWTONS SECOND LAW OF MOTION THE RATE OF CHANGE OF MOMENTUM IS DIRECTLY PROPORTIONAL TO THE APPLIED FORCE NOW,MOMENTUM(p)=mv
