(a) kgm/s

(b) kgm/s^2

(c) kgm/s^3

(d) kg.m^2

The question was posed to me by my college professor while I was bunking the class.

This intriguing question originated from Impulse Momentum Equation topic in division Fluid Dynamics of Fluid Mechanics

Answer 1

Right option is (a) kgm/s

The explanation: The SI unit of momentum is given by the product of the units of mass and velocity. In SI units, (mass is in kg) and (velocity is in m/s). As we know that momentum is mass times velocity. The unit turns out to be kgm/s.
