It also depends on the time during which the change occurs.
The formula is
Acceleration = (change in velocity) divided by (time for the change) .
Maybe Sla changed his velocity in 3 seconds, but Hazel
took all morning to change hers. In that case, even though
the amounts of change were equal, the times were different,
so the quotients of (change/time) were different.

Final answer:
The minimum dimensions for the rear-view mirror should be a height of 0.890 m and a width of 1.3 m.
Explanation:
In order for the driver to be able to see the entire width and height of the rear window in the rear-view mirror without moving their head, the mirror should have minimum dimensions that allow for this visibility. Let's calculate the minimum height and width required for the rear-view mirror.
Height of the mirror:The mirror should be half the height of the driver, which is given as 1.715 m at the top and 0.825 m at the bottom. Therefore, the height of the mirror should be 0.890 m (1.715 m - 0.825 m).Width of the mirror:The mirror should be wide enough to capture the entire width of the rear window. The width of the rear window is given as 1.3 m, so the width of the mirror should be at least 1.3 m. Therefore, the minimum dimensions of the rear-view mirror should be a height of 0.890 m and a width of 1.3 m.Learn more about rear-view mirror here:

The question is about Distance and Displacement. Distance, a scalar quantity, represents the total path length traveled between two positions, whereas displacement, a vector quantity, refers to the change in position from the starting to the final point, including direction.
When comparing distance and displacement in the field of science, specifically physics, there are key differences to keep in mind. Distance is a scalar quantity that refers to the total length of the path traveled between two positions. In contrast, displacement is a vector quantity—and thus includes both magnitude and direction—that represents the change in position of an object from its starting point to its end point.
Let's consider an example where you drive from home to school which is 5 km away, then return back home. In this case, the distance you traveled is 10 km because distance simply adds up all the lengths covered. However, the displacement is 0 km because displacement considers the direct path from the starting position to the final position; since you returned home, your initial and final positions are identical, and so the change in position is null.
Therefore, it's important to note that while distance and displacement can sometimes share the same magnitude, they are distinct in that displacement always includes direction. Distance is just a measure of how far an object has travelled, while displacement tells you how far and in which direction it is from the starting point.

Answer:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
