Taking velocity,force and time and the fundamental units find the dimension of mass
from the formula F= ma
m= F/a
putting the dimensions
m = [ M L T-2 ]/ [L T-2]
m = [M] which is the dimension of mass
If velocity (V), force(F) and time(t) are taken to be fundamental quantities and K is the dimensionless constant of proportionality, find the dimensional formula for mass.
