- Homework Statement
- A rotating wheel requires 3.00 s to complete 37.0 revolutions. Its angular speed at the end of the 3.00-s interval is 98.0 rad/s. What is the constant angular acceleration of the wheel?

- Relevant Equations
- a=(dw/dt)

w=(dtheta/dt)

wfinal=98.0 rad/s, dt=3.00s

w=(37 revs/3)=>w=(37 revs*(2*pi/1))/3=>w=77.493

a=(98-77.493)/3=>a=6.8357

My answer is exactly half of the correct answer. Where did I go wrong?
