## Questions 1-2
A cylinder rotates with constant angular acceleration about a fixed axis. The cylinder's moment of inertia about the axis is 4kgm2. At time t=0 the cylinder is at rest. At time t=2 seconds its angular velocity is 1 radian per second.

(A) 1 J
(B) 2 J
(C) 3 J
(D) 4 J
(E) cannot be determined without knowing the radius of the cylinder
