12. Rotational Kinematics / Equations of Rotational Motion / Problem 7
When a motor is switched off, rotational inertia and kinetic energy keep some parts rotating. A shaft experiences a steady decrease in angular frequency changing from 650 rev/min at t = 0 s to 300 rev/min at t = 3.50 s. At what time (t = ? not Δt) does the shaft stop assuming the angular accleration remains the same until it stops?
