## Homework Statement

Calculate the angular acceleration and angular velocity of a 2kg object rotating in a

circle of 1.5m radius in a time of 3s.

## Homework Equations

w=v/r

2*pie*r

## The Attempt at a Solution

Now i dont know how to fully work this out, not sure how to apply the forumla.

3 seconds for one complete roatation

360 / 3 = 120 degrees

120 degrees per second

2*pie*r=

9.42m

9.42 / 3 = 3.14ms-1

I know this completes 120 degrees going a distance of 3.14m in a second.

The question is how do i go about completing this question?
