Difference between Pascal’s law and law of flotation

Hi, I didn’t understand too well your question, but I hope this helps!

Archimedes principle is based on the weight of the object to push the object upward. Law of floation is the priciple which tells us about the density of the object with the liquid in which it is placed.

The car would move to the right with 150 n of force. the 150 n of force from friction and air resistance slows the car from moving to the right with 300 n of force.
