A car has a momentum of 20 comma 000 kilograms times m over s What would the car’s momentum be if its velocity doubles?

Momentum is mass times velocity, so if the car’s mass stays the same and its velocity doubles, its momentum doubles too. Double 20,000 kg·m/s to get 40,000 kg·m/s. The correct choice is 40,000 kilograms times m over s.
