Homework Statement
An object whose moment of inertia is 3.00kgm2experiences the torque shown in the figure (Figure 1) . What is the object's angular velocity at 2.80s ? Assume it starts from rest.

Homework Equations
Torque=angular acceleration * moment of inertia
angular velocity = angular acceleration * change in time
The Attempt at a Solution
From what I can understand of the problem, the angular acceleration is 0 (because torque is 0), but angular velocity is not zero so it must be some constant. However, I'm struggling how to figure out what that is.
