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

Explanation:

Step1: Recall the momentum formula

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

Step2: Substitute the given values

Given ( m = 2000 , \text{kg} ) and ( v = 20 , \text{m/s} ), substitute into the formula: ( p = 2000 \times 20 ).

Step3: Calculate the result

( 2000 \times 20 = 40000 , \text{kg·m/s} ).

Answer:

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