1. The problem statement, all variables and given/known data Calculate the angular acceleration and angular velocity of a 2kg object rotating in a circle of 1.5m radius in a time of 3s. 2. Relevant equations w=v/r 2*pie*r 3. 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?
