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 don't 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?
