The cable at Point B comes lose, and the pole rotates to the ground, starting from rest. a. What is the angular velocity, w, of the pole just before Point B hits the ground? b. What is the speed of the Point B just before it hits the ground? Ignore the mass of the flag. STATE 1 g STATE 2 |º B ľ 45% A A B 1m L=2.5 m w =? g
