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
