Hint: The momentum of a moving body is equal to the product of mass of the body and the velocity of the body. The S.I. unit of momentum is equal to product of S.I. units of mass and velocity.
Complete step by step answer:
A body in uniform motion has a constant velocity with which it moves. Velocity is a vector quantity and its magnitude gives the speed of the moving body. The momentum of a moving body is defined as the product of the mass of the body and the velocity of the body. It is a vector quantity denoted by symbol p. Mathematical expression for momentum is
$p = m{\text{v}}$
Greater the mass and velocity of the body, greater is its momentum.
The units are defined for the physical quantities to have a fixed standard for the measurement of different quantities. The most commonly used system of units is S.I. system.
The S.I. unit of mass is kilograms ($kg$). It is a fundamental quantity. Velocity is derived from the fundamental quantities, length and time and has S.I. units of metre per second ($m{s^{ - 1}}$).
The S.I. unit of momentum is equal to the product of S.I. units of mass and velocity, that is, kilogram metre per second ($kgm{s^{ - 1}}$)
Note: 1. The units of quantities related to each other should be in the same system. The units can be converted from one system to another easily.
2. Other systems of units commonly used are the C.G.S. system, M.K.S system, etc.
