[tex]48.93 Kg\frac{m}{s}[/tex] is the "momentum" of a kid.
Explanation:
"Momentum" of an object is defined as the "velocity" changed by an object by moving the object from "one place" to "another place". The "Momentum" of an object is represented as "[tex]p[/tex]". It is the product of the "mass of object" and the "velocity of object". It is mathematically written as [tex]p=m\times v[/tex].
Where, "m" is mass of object and "v" is velocity of object.
Given that,
Mass of a kid is 23.3 Kg.
Velocity of a kid is 2.1 m/s.
Now, to calculate momentum of the given object us the formula [tex]p=m\times v[/tex].
Plug the values,
[tex]p=23.3\times 2.1[/tex]
[tex]p=48.93 kg\frac m{s}[/tex]
