**1. The problem statement, all variables and given/known data**

A baton twirler throws a spinning baton directly upward. As it goes up and returns to the twirlers hands, the baton turns through four revolutions. Ignoring air resistance and assuming that the average angular speed is 1.80 rev/s, determine the height to which the center of the baton travels above the point of release.

**2. Relevant equations**

**3. The attempt at a solution**

I know that the total angular displacement is 25.13 radians and, therefore, the angular displacement the baton moves through to reach the maximum height is 12.565 radians. The anguar velocity which the baton experiences is 11.31 radians/sec. The total time of the trip is 2.2 seconds and the time to reach the top is 1.1 sec. Will the height reached by the centre of the baton be the radius? I can't quite get my mind around this angular displacement and velocity. I'm really stuck on this question.
