At the instant shown, the helicopter is moving upwards with a velocity = 4 ft/s and has an acceleration At the same instant the frame H, not the horizontal blade, rotates about a vertical axis with a constant angular velocity = 0.9 rad/s. If the tail blade B rotates with a constant angular velocity = 180 rad/s, measured relative to H, determine the velocity and acceleration of point P, located on the end of the blade, at the instant the blade is in the vertical position.
