Question

Describing Momentum Calculatthe momentum of cars A and answer the question Car A: Mass: 1,000 kilograms Velocity: 40 meters/second Car B: Mass: 4,000 kilograms Velocity 10 meters/second B, and then Which car is harder to stop and why?

Answer 1

neither A nor B because they have the same momentum

Step-by-step explanation:

Answer 2

Momentum is a protector the mass and the velocity of a moving object.
Momentum= mass*speed
For Car A: Mass:1,000 kilograms Velocity: 40 meters/second;
Momentum=1,000 kg*40 m/s
=40000kg.m/s
For Car B: Mass: 4,000 kilograms Velocity 10 meters/second;
Momentum=4000kg*10m/s
=40000kg.m/s
Both cars require the same amount of force to stop. This is because they have the same momentum.
