1. The problem statement, all variables and given/known data A body with moment of inertia 20kgm^2 is rotating about a fixed axis with an angular velocity of w(t)= 3t^2-4 a. Through what angular displacement will the body move in the first 3 seconds b. What is the new torque exerted on the object at t=2 2. Relevant equations Angular Kinematics equations 3. The attempt at a solution I integrated the angular velocity to get the displacement to be Theta(t)=t^3-4t ... then I evaluated the definite integral from 0 to 3 to get 15. But 15 What? Am I doing this right? I don't know what to do for the second part. Does anyone know?
