Using force, length, and time as fundamental quantities, what are the dimensions of mass?

```							Newton’s second law of motion states that, force acting on an object (F) from rest is equal to the mass of the object (m) times the acceleration of the object (a).So, F = ma …… (1)Rearranging the above equation, mass of the object (m) will bem = F/a …… (2)Acceleration of a body (a) is the rate of change of velocity (v) and velocity is the rate of change displacement (s).So, a = v/t = (s/t)/t = s/t2 …… (3)Since length and time as fundamental quantities, so the dimensions of acceleration will be[a] = [s/t2 ] = LT -2 …… (4)Using equation (2) and force, length, and time as fundamental quantities, the dimensions of mass would be,[m] = [F/a ] = F/ LT -2 = FL-1T2 …… (5)From equation (5), we observe that, using force, length, and time as fundamental quantities, the dimension of mass would be FL-1T2.
