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

a baton twirler throws a baton straight up in the air, it goes up and comes straight back down. it completes 4 rev. ignoring air resistance and assuming the 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**

i tried to use a kinematic eq. x=1/2(vnot+v)t

**3. The attempt at a solution[/b**

i tried that equation and solved for x, i put zero for vnot and 1.8 for v. i fount t to be 2.22 seconds i got my answer to be 2m but its wrong ...thanks!!
