Question

how much momentum does a 5 kg rock have if it is thrown at 8 m/s?
13
3
40
5

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 \( m = 5 \, \text{kg} \) and \( v = 8 \, \text{m/s} \), substitute into the formula: \( p = 5 \times 8 \).

Step3: Calculate the result

\( 5 \times 8 = 40 \).

Answer:

40
