A disk initially at rest is acted on by a constant net torque τ (think of this as force, F). The disk spins for a period of t seconds and rotates an angular distance of Δθ. The same disk is then brought to rest. The disk is now acted upon by a constant net torque 2τ (think of this as force, 2F). The disk spins for the same period of t seconds. What is the new angular distance the disk rotates?
