At the instant shown, the helicopter is moving upwards with a velocity of 4 ft/s and has an acceleration a=2 ft/s^s. At the same instant the frame h, not the horizontal blade, rotates about a vertical axis with a constant angular velocity w=0.9 rad/s, measured relative to h, derermine the velocity and acceleration of point P, located on the end of the blade, at the instant the blade is in the vertical position.
