Which of the following is not an appropriate unit for momentum? g•m/s kg•m/hr km•m/s g•cm/min

Option (c) is the correct answer.

Explanation:

Momentum is the product of mass and velocity.

Mathematically,       p = m × v

where       p = momentum

                m = mass

                v = velocity

It is known that mass can be measured in Kilograms or grams. Whereas velocity is measured in meter per second or centimeter per minute or hour.

On the other hand, unit kilometer is a unit of distance and not mass.

Thus, out of the given options km.m/s  is not an appropriate unit for momentum.

The answer is: km•m/s.

Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.

km (kilometer) is not unit for the mass, it is unit for distance.

For example:

p(ball) = 218 kg·m/s; momentum of a ball.
