Answer:

The answer in mixed number is [tex]=4\frac{0}{2}[/tex]

Step-by-step explanation:

Note: When a body is travelling at uniform acceleration, the average velocity is given as  [tex]Average -velocity= \frac{v+u}{2}\\\\[/tex]

Given

initial velocity u= 3 m/s

final velocity v= 5 m/s

[tex]Average -velocity= \frac{5+3}{2}\\\\[/tex]

[tex]Average-velocity= \frac{8}{2}[/tex]

To express this in mixed number we have [tex]=4\frac{0}{2}[/tex]
