Answer:
The distance moved is 28 meters. The displacement has a magnitude of 4 meters in direction to the west.
Explanation:
The dog walks 28 meters, so it is the distance moved, which is a scalar magnitude, so it doesn't consider the position of the dog.
The displacement is a vectorial magnitude, which consider the final and initial positions. The distance between the final and initial positions is the magnitude of the displacement. The direction is from the initial point to the final point from East to West.
It is used to reduce the friction
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.
Answer:
