An object is initially at rest, then it moves 100m east in four seconds then it travels 120m west in 6 seconds, what is the average velocity

Respuesta :

Answer:

1022

Explanation:

No recooil and wall hack and

[tex]\\ \bull\tt\longmapsto Avg\:Velocity=\dfrac{Total\:Displacement}{Total\:Time}[/tex]

First we have to find displacement

[tex]\\ \bull\tt\longmapsto Distaplacement=120-100=20m[/tex]

[tex]\\ \bull\tt\longmapsto Avg\:Velocity=\dfrac{20}{4+6}[/tex]

[tex]\\ \bull\tt\longmapsto Avg\:Velocity=\dfrac{20}{10}[/tex]

[tex]\\ \bull\tt\longmapsto Avg\:Velocity=2m/s[/tex]
