# A wheel with an I of 5.00 kg-m^2 starts at rest & accelerates under a constant torque of 3 N-M for 8 seconds. what is the wheel's rotational ke at the end of 8 seconds?

1. The rotational KE is always (1/2) I w^2

The angular acceleration when torque is applied is
alpha = (torque)/I

I am sure you can take it from there.
