3. The attempt at a solution

I thought I could take the second derivative and get the angular acceleration from which I could use where ω is the angular velocity, is the linear tangential acceleration, and r is the radius of curvature. But for some reason, it didn't give me the right answer, anyone know where I went wrong?
