Consider a helicopter lifting from ground. It follows a circular path of radius R in the vertical plane at a constant speed vo as shown, while maintaining its orientation so it always faces the center of the path. If its rotor is rotating at constant angular velocity of w... What are the velocity and acceleration of tip of the blade point P when 0 = and P is closest to the tail? TC Radius of the blade is r. At ground level, rotor's angular velocity is in along +k. Neglect the size of the helicopter. Z 0 R DOO y
