Answer» At what height the surface of earth does the acceleration a due to gravity become zero Let us consider an object of mass m, moving along a straight line with an initial velocity u. Let us say, after a certain time t, with a constant acceleration, the final velocity becomes v.Here we see that, the initial momentum(P1)=m*uThe final momentum(P2)=m*vThe change in momentum can be written as(P2-P1)=(m*v)-(m*u)=m(v-u)As we know, the rate of change of\xa0momentum\xa0with respect to time is proportional to the applied force. The applied forceF=m*a. |
