Question

a person with a mass of 15 kg is walking uphill at a velocity of 2 m/s. whats the walkers momentum? a) 13 kg-m/s b) 30 kg-m/s c) 10 kg-m/s d) 15 kg-m/s

Explanation:

Step1: Recall the momentum formula

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

Step2: Substitute the given values

Given \( m = 15 \, \text{kg} \) and \( v = 2 \, \text{m/s} \), substitute into the formula: \( p = 15 \times 2 \).

Step3: Calculate the result

\( 15 \times 2 = 30 \, \text{kg-m/s} \).

Answer:

B) 30 kg-m/s
