14. An object with a mass of 120 kilograms is moving at a velocity of [tex]30 \, \text{m/s}[/tex]. What is its momentum?

A. [tex]0.25 \, \text{kg} \cdot \text{m/s}[/tex]
B. [tex]4 \, \text{kg} \cdot \text{m/s}[/tex]
C. [tex]360 \, \text{kg} \cdot \text{m/s}[/tex]
D. [tex]3,600 \, \text{kg} \cdot \text{m/s}[/tex]


Sagot :

To determine the momentum of the object, we need to use the formula for momentum, which is given by:

[tex]\[ p = m \times v \][/tex]

where:
- [tex]\( p \)[/tex] is the momentum,
- [tex]\( m \)[/tex] is the mass of the object,
- [tex]\( v \)[/tex] is the velocity of the object.

Given:
- The mass ([tex]\( m \)[/tex]) of the object is 120 kilograms,
- The velocity ([tex]\( v \)[/tex]) of the object is [tex]\( 30 \, \text{m/s} \)[/tex].

Plugging these values into the formula, we get:

[tex]\[ p = 120 \, \text{kg} \times 30 \, \text{m/s} \][/tex]

When we multiply these values, we obtain:

[tex]\[ p = 3,600 \, \text{kg} \cdot \text{m/s} \][/tex]

Thus, the momentum of the object is [tex]\( 3,600 \, \text{kg} \cdot \text{m/s} \)[/tex].

The correct answer is:
D. [tex]\( 3,600 \, \text{kg} \cdot \text{m/s} \)[/tex]
