Question

what is the momentum of a 2000kg truck moving at a velocity of 20m/s?

Explanation:

Step1: Recall momentum formula

Momentum \( p \) is given by \( p = mv \), where \( m \) is mass and \( v \) is velocity.

Step2: Substitute values

Here, \( m = 2000 \, \text{kg} \) and \( v = 20 \, \text{m/s} \). So, \( p = 2000 \times 20 \).

Step3: Calculate the product

\( 2000 \times 20 = 40000 \).

Answer:

The momentum of the truck is \( 40000 \, \text{kg·m/s} \) (or \( 4 \times 10^4 \, \text{kg·m/s} \)).
