Question

a 2 kg ball is moving at 3 m/s. what is its momentum? $p = mv$
5 kg·m/s
1.5 kg·m/s
6 kg·m/s
0.67 kg·m/s

Explanation:

Step1: Identify given values

Mass $m = 2\ \text{kg}$, velocity $v = 3\ \text{m/s}$

Step2: Apply momentum formula

Use $p = mv$
$p = 2\ \text{kg} \times 3\ \text{m/s}$

Step3: Calculate the product

$p = 6\ \text{kg·m/s}$

Answer:

6 kg·m/s (corresponding to the option: 6 kg·m/s)
