Kilogram meter per second is unit of
 A Frequency B Angle Velocity C Momentum D Moment of Inertia
Explanation:

Detailed explanation-1: -The kilogram-meter per second (kg · m/s or kg · m · s-1 ) is the standard unit of momentum . Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N · s), which is the SI unit of impulse.

Detailed explanation-2: -As mentioned above, the units of momentum will be the product of the units of mass and velocity. Mass is measured in kg and velocity in ms-1, therefore, the SI unit of momentum will be kgm/s(-1).

Detailed explanation-3: -Kg ms-2 is also called Newton as unit of force is newton. Q.

Detailed explanation-4: -Hence, the SI unit for momentum in physics can also be Newton-second (Ns). In the CGS system, the mass of an object is considered in grams, and velocity is considered in terms of centimeters per second. Therefore, the unit of momentum is gram-centimeters per second (g⋅cm/s). The standard unit of momentum is kg*m/s.
