This is basic application of kinematics concerning rotation and angular acceleration. What do you think?

The formulae are the same as those for linear acceleration: Substitute: Torque τ for Force F Moment of inertia I for Mass m Angular acceleration α for Linear acceleration a Then substitute: Angular velocity ω for Linear velocity v Angular displacement θ for Linear displacement s (or x)

Remember formula: \tau = I*\alpha. Solve for \alpha. Then 2*\pi = 1/2*\alpha*t^2 and solve for t.
