The discussion revolves around the relationship between angular velocity and tangential velocity in the context of a discus throw. The problem involves calculating the speed of the discus at release after one complete revolution, given the diameter of the circular path and the time taken for the revolution.
Participants are actively engaging with the problem, with some providing hints and guidance on how to approach the conversion from angular to tangential velocity. There is a recognition of the need to express the final answer in meters per second, which has led to further exploration of the relevant equations.
Participants note the requirement to convert angular measurements to linear speed, highlighting the challenge of transitioning from radians per second to meters per second in their calculations.

To throw the discus, the thrower holds the discus with a fully outstretched arm and makes one revolution as rapidly as possible to give maximum speed to the discus at release. The diameter of the circle in which the discus moves is about 1.7m.
If the thrower takes 1.0s to complete one revolution, starting from rest, what will be the speed of the discus at release?

The Attempt at a Solution
I found the angular acceleration to be 2pi rad/s. I just don't know how to find the speed from there..
