Suppose an object having mass m has an initial velocity u and after certain time t it attains a velocity v. Now momentum P1=mu and P2=mv So change in momentum =P2-P1=mv-mu =m(v-u) So the rate of change...
As we know, exam time is most difficult for the student whether they study correctly or not. This time is also required mental preparation which comes through more than ten times revision and then memories...
