An object traveling along the x-axis has a velocity of 2.0 m/s from 0 to 4.0 s, 0 m/s from 4.0 to 6.0 s, -2.0 m/s from 6.0 to 8.0 s, and 4.0 m/s from 8.0 to 10 s. what is the average velocity of the object from 0 to 10 s?

Explanation:

Given

object travelling with 2 m/s from 0 to 4 s

0 m/s from 4 to 6 s

-2 m/s from 6 to 8 s

4 m/s from 8 to 10 s

Average velocity

Also v-t graph displacement can be figured out

therefore displacement

average velocity

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
