## Homework Statement

Using your data from trial one, calculate angular velocity w, and angular acceleration, a

My data from trial one is period of rotation=.791s

## Homework Equations

w=(change in angle/change in time)

a=(change in angular velocity/ change in time)

## The Attempt at a Solution

avg w=360deg/.791s= 455deg/s

avg a=(455deg/s)/.791= 575deg/s^2

I believe this is correct but I thought I would ask anyways. I asked my teacher several days ago whether the question was asking for average or instantaneous velocity/acceleration and he hasn't responded and it is past due so if anyone would like to comment on what they think about that.( The question I posted is word for word) also I am having trouble understanding the concept of instantaneous angular velocity because as the time is approaching zero then so is the angle so I dont see the point. thanks in advance for any help.
