Select the correct answer.

What is the momentum of a 35-kilogram cart moving at a speed of 1.2 meters/second?

A. 42 kilogram meters/second
B. 70 kilogram meters/second
C. [tex]$4.2 \times 10^2$[/tex] kilogram meters/second
D. [tex]$7.0 \times 10^2$[/tex] kilogram meters/second



Answer :

To determine the momentum of the cart, we'll use the formula for momentum in physics:

[tex]\[ \text{momentum} = \text{mass} \times \text{velocity} \][/tex]

Given:
- Mass (\( m \)) = 35 kilograms
- Velocity (\( v \)) = 1.2 meters/second

Plugging these values into the formula:

[tex]\[ \text{momentum} = 35 \, \text{kg} \times 1.2 \, \text{m/s} \][/tex]

[tex]\[ \text{momentum} = 42 \, \text{kilogram meters/second} \][/tex]

Therefore, the correct answer is:

A. 42 kilogram meters/second
