Question

question 9 of 20 : select the best answer for the question. 9. a person with a mass of 15 kg is walking uphill at a velocity of 2 m/s. whats the walkers momentum?
a. 30 kg-m/s
b. 10 kg-m/s
c. 15 kg-m/s
d. 13 kg-m/s
mark for review (will be highlighted on the review page)

Explanation:

Step1: Recall momentum formula

Momentum \( p \) is calculated by the formula \( p = m \times v \), where \( m \) is mass and \( v \) is velocity.

Step2: Substitute values

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

Step3: Calculate result

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

Answer:

A. 30 kg - m/s
