What is the momentum of a 5 kg object that has a velocity of 1.2 m/s?

A. 3.8 kg·m/s
B. 4.2 kg·m/s
C. 6.0 kg·m/s
D. 6.2 kg·m/s

Sagot :

To determine the momentum of an object, you can use the formula:

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

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

Given:
- [tex]\( m = 5 \text{ kg} \)[/tex]
- [tex]\( v = 1.2 \text{ m/s} \)[/tex]

Let's substitute the given values into the formula:

[tex]\[ p = 5 \text{ kg} \cdot 1.2 \text{ m/s} \][/tex]

To calculate the momentum [tex]\( p \)[/tex]:

[tex]\[ p = 6.0 \text{ kg} \cdot \text{m/s} \][/tex]

Therefore, the momentum of the object is [tex]\( 6.0 \text{ kg} \cdot \text{m/s} \)[/tex].

The correct option is:
[tex]\[ \boxed{6.0 \text{ kg} \cdot \text{m/s}} \][/tex]
