Angular Impulse and Momentum
A disk, initially at rest, is subjected to a constant torque τ for a time interval Δt. The torque is then reversed to -τ and applied for another time interval of Δt. What is the final angular momentum of the disk?
A
Zero
B
τΔt
C
Depends on the moment of inertia of the disk
D
2τΔt
