w^2=w(initial)^2 + 2(alpha)(delta theta)

Then I found I by using I = (1/2)mr^2

I them multiplied the two answers together to get the torque since

Torque = I(alpha)

Like I said, this worked to find the answer using the books numbers but it didn't work for my homework. (The books numbers are (W final = 0 rad/s, w initial = 1.22 rad/s, radius is 0.71m. The rest is the same. The answer is 0.25) Please help
