							2nd one isVelocity =displacement divided by the time interval i.e s/t, thus diamensional formula becomes. [L^1T^-1]Now,Impulse is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector in the same direction.THUS, it have diamensional formula [L^1T^-1]THUS, VELOCITY AND IMPULSE HAVE DIAMENSIONAL FORMULA=[L^1T^-1]
