A wind farm generator uses a two-bladed propeller (see figure)mounted on a pylon at a height of 20 m.The length of each propeller blade is 12 m.A small piece from the tip of the propeller breaks off when the propeller is vertical.At that instant,the period of the motion of the propeller is .The fragment flies off horizontally,falls with negligible air resistance,and strikes the ground at P.
(a)How far is point P from the base of the pylon?
(b)At what angle with respect to the vertical is the fragment moving just as it strikes the ground at P?
