Concept- To begin, we'll calculate the velocity dimensional formula in primary dimensions.  Then, using this dimensional formula, we'll plug it into the momentum formula.
Momentum (M) = Mass Question Image Velocity………….(1)
The dimensional formula of velocity Question Image (2)
And, the dimensional formula of mass Question Image (3)
Equation (1) is obtained by substituting equations (2) and (3) .
Momentum = Mass Question Image Velocity
Or, Question ImageTherefore, momentum is dimensionally represented as Question Image.
