A red cart has a mass of 4 kg and a velocity of 5 m/s. There is a 2-kg blue cart that is parked and not moving, thus its velocit
y is 0 m/s. The red cart hits the blue cart.
The blue cart starts to move forward with a velocity of 6 m/s. The red cart bounces off of the blue cart and moves backwards, at a velocity of 2 m/s.
Name the TYPE of collision that occurred.
Calculate the BEFORE momentum of the red cart. Use correct units.
Calculate the BEFORE momentum of the blue cart. Use correct units.
Calculate the AFTER momentum of the red cart. Use correct units.
Calculate the AFTER momentum of the blue cart. Use correct units.
Calculate the SYSTEM’S TOTAL MOMENTUM before the collision. Use correct units.
Calculate the SYSTEM’S TOTAL MOMENTUM after the collision. Use correct units.
EXPLAIN how this example supports the Law of Conservation of Momentum. Use the evidence to support your answer of how this example supports the Law of Conservation of Momentum. Use correct units. Be specific.
Explanation: The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions.
