Explanation:

Step1: Recall the formula for momentum

The formula for momentum \( p \) is \( p = m \times v \), where \( m \) is the mass and \( v \) is the velocity.

Step2: Substitute the given values

Given \( m = 120 \) kg and \( v = 60 \) m/s. Substitute these values into the formula: \( p = 120 \times 60 \).

Step3: Calculate the product

\( 120 \times 60 = 7200 \) kg - m/s.

Answer:

B. 7,200 kg - m/s
