A certain wheel has a rotational inertia of 12 kg m2. As it turns through 5.0 rev its angular velocity increases from 5.0 rad/s to 6.0 rad/s. If the net torque is constant, its value is:

2. Relevant equations

Angular acceleration = dW/dT

Net torque = (angular acceleration)*(rotational inertia)

Θ_{f}= Θ_{i}+ (W_{i})(dT) + [tex]\frac{1}{2}[/tex] [tex]\alpha[/tex][tex]\Delta[/tex]t^{2}

3. The attempt at a solution

I have dW = 5-6=-1rad/s

I am confused on how to find dT. The equations have have both have two unknowns (t & [tex]\alpha[/tex])
