Question

an object has a mass of 5 kg and a velocity of 20 m/s. what is the momentum of the object? (1 point)

4 kg·m/s

0.25 kg·m/s

25 kg·m/s

100 kg·m/s

Explanation:

Step1: Recall momentum formula

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

Step2: Substitute values

Given \( m = 5 \, \text{kg} \) and \( v = 20 \, \text{m/s} \), substitute into the formula: \( p = 5 \times 20 \).

Step3: Calculate result

\( 5 \times 20 = 100 \, \text{kg·m/s} \).

Answer:

100 kg·m/s (corresponding to the option "100 kg·m/s")
