A boxer receives a horizontal blow to the head that topples him over. The force, of magnitude 1.40 103 N, is applied for 2.0 10-2 s at a point 1.65 m above the floor. The boxer has a moment of inertia of 77.0 kg · m2 for rotation about an axis at his feet.
(a) Find the boxer's final angular velocity.
(b) How long would it take him to hit the floor if he continued with the same angular velocity?
