Answer:
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 [tex]=\frac{Displacement }{time}[/tex]
Also v-t graph displacement can be figured out
therefore displacement [tex]=2\times 4+0-2\times 2+4\times 2=12 m[/tex]
average velocity[tex]=\frac{12}{10}=1.2 m/s[/tex]
