## Homework Statement

In circular motion what will be the change in velocity if initial velocity and final velocity is 2 m/s? From the left, in the 3rd diagram, if initial velocity and final velocity is 2 m/ s then what is the change in velocity? t = 5 s

## Homework Equations

## The Attempt at a Solution

the answer should be.

Acceleration = Vf - Vi / t = (-2i) - 2i / 5 = -4i / 5 = -0.8 m/s^2 but the answer is 0.8m/s^2.
